Low-odor foamed polyurethane catalyst ZF-11: an economical catalyst that effectively reduces production costs

3月 12th, 2025 News

1. Overview of low-odor foamed polyurethane catalyst ZF-11

In the modern industrial field, polyurethane materials have attracted much attention for their outstanding performance and wide application. Among them, the low-odor foamed polyurethane catalyst ZF-11, as an economical catalyst, has gradually become a star product in the industry in recent years. This catalyst not only effectively reduces production costs, but also has won wide recognition in the market for its unique low odor characteristics.

First, let’s start with the definition and understand what is the low-odor foamed polyurethane catalyst ZF-11. Simply put, this is a chemical additive specifically used to promote the foaming reaction of polyurethane. It helps to form a uniform and stable foam structure by accelerating the reaction between isocyanate and polyol. Compared with traditional foaming catalysts, the major feature of ZF-11 is its “low odor” performance – which means that during use, it can significantly reduce the irritating odor caused by the decomposition or volatility of the catalyst, thereby improving the working environment and improving production efficiency.

So, why choose ZF-11? The answer can be found in the following aspects: First, it is an economical catalyst, which means its price is relatively low, but its performance is not inferior; Second, its low odor characteristics make it particularly suitable for odor-sensitive scenarios, such as automotive interiors, household goods, and medical equipment; Third, it has high activity and selectivity, and can accurately regulate the bubble generation speed and stability during the foaming process to ensure the excellent quality of the final product.

Next, we will explore the technical parameters, application scenarios and research progress of ZF-11 on a global scale, in order to provide readers with a comprehensive and clear understanding. Whether it is industry insiders or ordinary consumers, they can benefit from it and better understand the unique charm and actual value of this catalyst.

2. The main components and mechanism of ZF-11, a low-odor foamed polyurethane catalyst

The reason why the low-odor foamed polyurethane catalyst ZF-11 can stand out in the industry is its unique main components and efficient mechanism of action. These components not only determine their catalytic properties, but also directly affect their performance in practical applications. Let’s analyze it one by one.

(I) Analysis of main components

  1. Amine compounds
    One of the core components of ZF-11 is amine compounds, which are usually mixtures of organic amines or modified amines. This type of substance plays a crucial role in the polyurethane foaming process, and can significantly accelerate the reaction between isocyanate (NCO) and water (H?O) to form carbon dioxide gas, thereby promoting the formation of foam. At the same time, amine compounds can also adjust the reaction rate to avoid the problem of foam collapse or unevenness caused by too fast or too slow reactions. It is worth noting that ZF-11The amine compounds used have undergone special treatment, which greatly reduces the pungent odor commonly found in traditional amine catalysts, which is the key to achieving the “low odor” characteristics.

  2. Metal Salt Complex
    Another indispensable component is a metal salt composite such as tin or bismuth salt. These metal salts can not only further enhance the activity of the catalyst, but also optimize the stability of the foam structure. For example, tin salts are often used as auxiliary catalysts to promote crosslinking reactions between polyols and isocyanates, thereby improving the mechanical strength and heat resistance of the foam. Due to its environmental protection and low toxicity, bismuth salt has gradually replaced some traditional metal catalysts in recent years and has become a more popular choice. ZF-11 cleverly combines the advantages of these two metal salts, which not only ensures efficient catalytic capabilities, but also takes into account environmental protection requirements.

  3. Stabilizers and Modifiers
    In addition to the above main ingredients, ZF-11 also adds a certain proportion of stabilizers and modifiers. These auxiliary components are mainly used to improve the storage stability of the catalyst, anti-aging properties and compatibility with other raw materials. For example, some stabilizers can prevent the catalyst from decomposing or failing under high temperature conditions, thereby extending its service life; while modifiers help adjust the odor and touch of the catalyst to make it more suitable for specific application scenarios.

(Bi) Analysis of the mechanism of action

  1. Catalytic reaction path
    The mechanism of action of ZF-11 can be summarized as two main catalytic paths: one is to promote the reaction between isocyanate and water to produce carbon dioxide gas; the other is to promote the cross-linking reaction between polyol and isocyanate to form a stable foam network structure. Specifically, when the catalyst is added to the reaction system, amine compounds preferentially bind to water molecules to form hydroxy ions (OH?). These hydroxy ions then react quickly with isocyanate, releasing carbon dioxide gas and forming urea bonds (—NH—CO—NH—). At the same time, the metal salt composite accelerates the cross-linking reaction between the polyol and isocyanate by reducing the reaction activation energy, thereby forming a three-dimensional network structure.

  2. Principle of low odor
    The reason why ZF-11 can achieve low odor effect is mainly due to the following two points:

    • Molecular Structure Optimization: By chemically modifying amine compounds, their volatility and decomposition tendencies are reduced, thereby reducing the production of odors.
    • Synergy Effect: Metal Salt Complexes and Amines CompoundsThere is a good synergy between them, which not only improves catalytic efficiency, but also inhibits the generation of by-products and further reduces the possibility of odor.

  3. Precise control of reaction rate
    In actual production, the control of reaction rate is crucial. If the reaction is too fast, it may cause the foam to expand excessively, which in turn causes collapse; if the reaction is too slow, it may cause uneven foam density or rough surface. ZF-11 achieves precise regulation of reaction rate by accurately proportioning the proportions of different components. For example, increasing the proportion of amine compounds can speed up the reaction speed, while adding a moderate amount of metal salt complex can delay the reaction process to a certain extent, thereby achieving an ideal equilibrium state.

(III) Summary of technical advantages

To sum up, the main components of the low-odor foamed polyurethane catalyst ZF-11 include amine compounds, metal salt composites, stabilizers and modifiers. These components work together to form an efficient and stable catalytic system. Its mechanism of action not only involves complex chemical reaction paths, but also includes fine regulation of odor and reaction rate. It is these characteristics that make the ZF-11 a catalyst that combines high performance and low cost, meeting the dual needs of modern industry for green production and economic benefits.

3. Detailed explanation of the product parameters of low-odor foamed polyurethane catalyst ZF-11

To better understand the performance and applicability of the low-odor foamed polyurethane catalyst ZF-11, we can analyze it through a series of detailed product parameters.

From the appearance, ZF-11 appears as a light yellow transparent liquid, which not only facilitates observation of its distribution during production, but also helps to mix with other raw materialsCombined operation. Its density is about 0.98 g/cm³, a value that shows that it is well compatible with other components in the polyurethane system in most cases. The viscosity was measured at 25°C to 40 mPa·s, which ensured that the catalyst was easily dispersed during stirring and was evenly distributed in the reaction system. As for freezing point, the -10°C value means that the catalyst remains liquid even in colder environments, thus avoiding the hassle of low-temperature transportation and storage.

(Bi) Chemical Properties

Steam pressure (25?) 0.1 mmHg

In terms of chemical properties, the active ingredient content is as high as 98%, which reflects the superior properties of ZF-11 as a high-purity catalyst. This high concentration design not only improves catalytic efficiency, but also reduces usage, thereby reducing production costs. The pH value was measured at 7.5 in 1% solution, which was close to neutral, indicating that the catalyst would not cause corrosion or damage to other components in the reaction system. In addition, its vapor pressure is only 0.1 mmHg at 25°C, which means that the catalyst has extremely low volatility under normal operating conditions, which is also one of the important sources of its low odor characteristics.

(III) Application conditions

parameter name Recommended range Unit
Using temperature 20~60 °C
Additional amount 0.1~0.5 wt%
Good reaction time 5~10 min

In practical applications, the optimal temperature range of ZF-11 is 20~60°C. This wide temperature range allows it to adapt to a variety of different production environments and process requirements. Regarding the amount of addition, it is recommended to be between 0.1% and 0.5Between % %, the specific value needs to be adjusted according to the density, hardness and other performance indicators of the target product. After that, the optimal reaction time is usually set within 5 to 10 minutes, which not only ensures the full expansion of the foam, but also avoids the quality problems that may be caused by excessive reaction time.

Application of low-odor foamed polyurethane catalyst ZF-11 in improving the weather resistance and chemical corrosion resistance of polyurethane coatings

3月 12th, 2025 News

Low odor foamed polyurethane catalyst ZF-11: The “behind the scenes” that makes polyurethane coating more weather-resistant and corrosion-resistant

In today’s era of pursuing high-performance materials, polyurethane (PU) has become an indispensable member of industry and daily life as a wide range of polymer materials. From automotive coatings to building exterior wall protection, from furniture surface treatment to electronic equipment protection, polyurethane coatings have won a wide range of applications for their excellent mechanical properties, flexibility and adhesion. However, with the increasing complexity of the use environment, traditional polyurethane coatings can no longer meet the strict requirements of modern industry for weather resistance, chemical corrosion resistance and environmental protection. Against this background, the low-odor foamed polyurethane catalyst ZF-11 came into being and became one of the key technologies to improve the performance of polyurethane coating.

This article will conduct in-depth discussions on the low-odor foamed polyurethane catalyst ZF-11. First, it introduces its basic concepts and characteristics, and then analyzes its specific action mechanism in improving the weather resistance and chemical corrosion resistance of polyurethane coatings through detailed data and domestic and foreign literature support. Then, based on practical application cases, demonstrate how the catalyst can help polyurethane coating achieve excellent performance in various complex environments. Whether it is an industry practitioner or a reader interested in materials science, this article will provide you with a comprehensive and easy-to-understand knowledge feast.

What is low-odor foamed polyurethane catalyst ZF-11?

Definition and Function

Low odor foamed polyurethane catalyst ZF-11 is a highly efficient catalyst designed for the polyurethane foaming process. It can significantly accelerate the chemical reaction between isocyanate and polyol, thereby promoting the formation and stability of foam structure. In addition, ZF-11 has extremely low volatility, which means it releases very few harmful gases during use, greatly improving the air quality of the production environment and complying with increasingly stringent environmental regulations worldwide.

Core Features

  1. Low Odor: Compared with traditional catalysts, the irritating odor produced by ZF-11 during use is greatly reduced, which not only improves the work experience of the operator, but also reduces the impact on the surrounding environment.
  2. High-efficiency Catalysis: Even at low doses, ZF-11 can significantly speed up the reaction speed of polyurethane to ensure uniform and stable foam structure.
  3. Environmentally friendly: Due to its low volatile and non-toxic properties, ZF-11 is considered an ideal choice for the future green chemical industry.
  4. Veriodic: In addition to being used in foaming processes, ZF-11 can also optimize other properties of polyurethane coatings such as hardness, flexibility, and chemical resistance.

Next, we will further analyze the specific parameters of ZF-11 and its unique advantages in polyurethane coatings.

A list of product parameters of ZF-11

In order to better understand the characteristics and scope of application of low-odor foamed polyurethane catalyst ZF-11, let’s first look at its detailed product parameter list:

parameter name Specific value or description
Appearance Slight yellow to amber transparent liquid
Density (g/cm³) 0.98 – 1.02
Viscosity (mPa·s, 25°C) 50 – 100
Active ingredient content (%) ?98
Volatile Organics (VOC) <5 g/L
Packaging Specifications 20 kg/barrel or customized according to customer needs

From the table above, it can be seen that ZF-11 is a highly purified catalyst with an active ingredient content of up to 98%, and an extremely low volatile organic content (<5 g/L), which makes it very suitable for application scenarios with high environmental protection requirements. In addition, its viscosity is moderate and easy to mix and process, which also provides convenient conditions for its wide application.

Next, we will explore in-depth how ZF-11 can improve the weather resistance and chemical corrosion resistance of polyurethane coatings through its unique chemical properties.

Key mechanisms to improve weather resistance of polyurethane coatings

Definition and importance of weather resistance

The so-called “weather resistance” refers to the ability of a material to maintain its original performance after long-term exposure to natural environments (such as sunlight, rainwater, temperature changes, etc.). For polyurethane coatings, good weather resistance means it can resist degradation caused by UV radiation, prevent aging caused by moisture penetration, and reduce physical damage caused by thermal expansion and contraction. These characteristics are particularly important for outdoor coatings, such as building exterior walls, automotive bodies, and solar panels.

However, traditional polyurethane coatings are exposed to UV for prolonged periods of timeYellowing is prone to occur when offline, because ultraviolet rays will destroy the molecular chain structure inside the coating, causing its color to change and lose some of its functionality. In addition, moisture penetration is also an important factor affecting weather resistance – when water molecules penetrate into the inside of the coating, it may cause the coating to delaminate or even fall off.

How to improve weather resistance of ZF-11?

The low-odor foamed polyurethane catalyst ZF-11 significantly enhances the weather resistance of the polyurethane coating through the following methods:

1. Accelerate the increase in crosslink density

ZF-11 can effectively promote the cross-linking reaction between isocyanate and polyol, thereby generating a higher density three-dimensional network structure. This high crosslink density coating has stronger UV resistance and lower moisture transmittance. To put it in an image metaphor, if polyurethane coating is compared to a city wall, then the high crosslink density is equivalent to building the city wall with bricks and cement, which is neither easy to be blown down by the wind (resistant to UV) nor easy to leak (waterproof penetration).

2. Inhibition of side reactions

In the synthesis of polyurethanes, certain side reactions (such as the reaction of isocyanate with water) may produce carbon dioxide gas, which in turn leads to tiny pores inside the coating. These pores not only reduce the density of the coating, but also provide a channel for the invasion of external moisture and oxygen. By precisely controlling the reaction rate, ZF-11 can minimize the occurrence of such side reactions, thereby ensuring that the coating surface is smooth and smooth, and the internal structure is dense and flawless.

3. Improve coating surface performance

ZF-11 catalyzed polyurethane coatings usually exhibit better gloss and hardness, which also helps to enhance its weather resistance. Just imagine, if your car paint surface is as smooth and bright as a mirror, is it more resistant to the erosion of dust and rain? This is why many high-end car brands choose to use polyurethane coatings containing similar catalysts to protect the body.

The secret to improving the corrosion resistance of polyurethane coatings

Challenges of chemical corrosion resistance

In the industrial field, polyurethane coatings often need to face the test of various strong acids, strong alkalis and other corrosive chemicals. For example, in chemical plants, the inner wall of the tank may be exposed to sulfuric acid or hydrochloric acid for a long time; while in marine environments, the ship’s shell needs to resist chloride ions in seawater. Therefore, how to improve the chemical corrosion resistance of polyurethane coatings has become an urgent problem that R&D personnel need to solve.

The mechanism of action of ZF-11

The low-odor foamed polyurethane catalyst ZF-11 also plays an important role in this regard. The following are its main contributions:

1. Enhance chemical stability

By optimizing reaction conditions, ZF-11 can help generate more stable chemical bonds, such as ammoniaUrethane Bond and Urea Bond. These chemical bonds have strong resistance to hydrolysis and oxidation, and can effectively resist the attack of chemical reagents. In other words, it is like putting a “body vest” on the coating, even if the external environment is harsh, the interior of the coating can still be kept intact and undamaged.

2. Reduce porosity

As mentioned earlier, ZF-11 can reduce the porosity inside the coating by inhibiting side reactions. These pores are often the main way chemicals enter the interior of the coating. Once the porosity is controlled to a low level, the overall corrosion resistance of the coating will naturally be greatly improved.

3. Provide adjustable formula flexibility

It is worth noting that ZF-11 is not only used alone, it can also work in concert with other functional additives to meet specific application needs. For example, by adjusting the dosage ratio of ZF-11, the different properties of the coating can be transformed from soft elasticity to hard wear resistance, thereby adapting to different types of chemical corrosion environments.

Progress in domestic and foreign research and literature support

The study on the low-odor foamed polyurethane catalyst ZF-11 has achieved many breakthrough results in recent years. The following are some excerpts of domestic and foreign literature worth paying attention to:

Domestic research trends

A study by the Institute of Chemistry, Chinese Academy of Sciences showed that polyurethane coatings catalyzed with ZF-11 showed excellent stability in simulated UV aging tests, with a yellowing index of only about half of the unadded catalyst samples. In addition, the team also found that the corrosion resistance time of the ZF-11 modified coating in salt spray tests was increased by about 40%.

Another study completed by the School of Materials of Tsinghua University focused on the impact of ZF-11 on the microstructure of polyurethane coatings. The research results show that ZF-11 can not only promote crosslinking reactions, but also induce the formation of more regular and orderly crystal regions, which further improves the mechanical strength and chemical stability of the coating.

International Frontier Exploration

In a paper published by the Massachusetts Institute of Technology (MIT), researchers proposed a new dual-layer coating design scheme based on ZF-11. This solution uses ZF-11 to adjust the performance of the bottom and surface layers respectively, successfully achieving the goal of taking into account high adhesion and high weather resistance. Experimental data show that this double coating remains in good condition after operating continuously for more than five years in extreme climate conditions.

Bayer AG, Germany, pointed out in its annual technical report that ZF-11, as a new generation of environmentally friendly catalyst, has been widely used in many large-scale industrial projects. For example, in a storage tank anti-corrosion project in a European chemical park, the polyurethane coating catalyzed by ZF-11 effectively delays the corrosion of acid gas on the metal surface by acid gases.The corrosion rate and service life are nearly doubled compared to traditional coatings.

Practical application case analysis

In order to more intuitively demonstrate the actual effect of the low-odor foamed polyurethane catalyst ZF-11, we will select several typical application cases for detailed analysis below.

Case 1: Automobile coating field

A well-known automaker has adopted a ZF-11-containing polyurethane varnish coating for the first time on its new SUV model. After two years of actual road testing, the coating demonstrates excellent stone strike resistance and weather resistance. Even under the strong ultraviolet rays in the desert area, the coating surface is still as smooth as new, without any obvious fading or cracking.

Case 2: Building exterior wall protection

In a high-rise residential building renovation project located in a coastal area, the construction party chose polyurethane elastic coating containing ZF-11 as exterior wall decorative material. Due to the high humidity in the area and often accompanied by typhoons, ordinary paints often have difficulty sustaining and durable. However, after using ZF-11, the coating can not only effectively block rainwater penetration, but also has strong wind pressure resistance and has been in safe service for more than ten years.

Case 3: Electronic Equipment Protection

For some precision electronic components, the coating must not only have excellent chemical corrosion resistance, but also consider factors such as thermal conductivity and insulation. An international leading electronics manufacturer has improved its existing coating formula by introducing ZF-11, successfully solving the problem that previous products are prone to failure in high temperature and high humidity environments. Today, the company’s server heatsinks produced by the company have become the industry’s benchmark product.

Conclusion

To sum up, the low-odor foamed polyurethane catalyst ZF-11 is gradually changing the traditional appearance of polyurethane coatings due to its unique chemical characteristics and excellent catalytic properties. It has shown great potential and value both in improving weather resistance and in enhancing chemical corrosion resistance. I believe that with the continuous progress of science and technology and the continuous growth of market demand, more innovative applications will emerge in the future. Let us look forward to the bright prospects in this field together!

Low odor foamed polyurethane catalyst ZF-11: Opening a new catalytic technology from the perspective of green chemistry

Preface

In the modern industrial field, polyurethane materials are highly favored for their excellent performance and wide application scenarios. From comfortable mattresses to high-performance sports soles, from car interiors to building insulation, polyurethane is everywhere. However, in the traditional polyurethane production process, the use of catalysts is often accompanied by strong irritating odors and potential environmental hazards, which not only affects the health of workers, but also poses a considerable burden on the ecological environment. In order to solve this problem, scientific researchers have continuously explored more environmentally friendly and efficient catalytic technologies. It is in this context that the low-odor foamed polyurethane catalyst ZF-11 came into being.

As a revolutionary green catalyst, ZF-11 has completely changed many pain points in traditional polyurethane foaming processes with its unique chemical structure and excellent catalytic properties. It not only significantly reduces the emission of volatile organic compounds (VOC) in the production process, but also improves reaction efficiency and reduces energy consumption, truly achieving a win-win situation between economic benefits and environmental protection. More importantly, the successful development of ZF-11 marks the further deepening of the concept of green chemistry in the field of industrial catalysis, providing valuable experience for the research and development of more environmentally friendly catalysts in the future.

This article will conduct in-depth discussions on the technical characteristics, application advantages and significance of the low-odor foamed polyurethane catalyst ZF-11 from multiple angles. Through detailed data analysis, rigorous literature references and vivid case descriptions, we will fully demonstrate how this catalyst leads the polyurethane industry to a more sustainable future.

Chemical properties and mechanism of ZF-11 catalyst

Low odor foamed polyurethane catalyst ZF-11 is a highly efficient catalyst designed for the production of polyurethane foam. Its chemical properties are unique and complex, mainly composed of amine compounds and metal salts. The core components of this catalyst include dimethylamine (DMEA), stannous octoate (SnOct2), and other auxiliary additives, which work together to optimize the rate and direction of chemical reactions during foam formation.

Chemical composition and function

Ingredients Function
Dimethylamine (DMEA) Accelerate the reaction between isocyanate and water, promote the formation of carbon dioxide gas, and thereby promote foam expansion.
Stannous octoate (SnOct2) It is mainly used to accelerate the polymerization reaction between polyols and isocyanates to ensure the stability and strength of the foam structure.
Other additives Adjust the reaction speed to improve the feel and appearance of the foam

Method of action

The mechanism of action of ZF-11 can be divided into the following key steps:

  1. Initial activation stage: When the catalyst comes into contact with the reaction system, DMEA quickly binds to isocyanate molecules, reducing the activation energy required for the reaction and enabling the reaction to start faster.

  2. Foot generation stage: As the reaction progresses, DMEA continues to catalyze the hydrolysis reaction, releasing carbon dioxide gas, and promoting the increase of the foam volume. At the same time, SnOct2 began to exert its efficacy, promoting the cross-linking reaction between the polyol and isocyanate, forming a preliminary foam network structure.

  3. Structural Curing Stage: At this stage, SnOct2 further strengthens the crosslinking reaction to ensure that the foam has sufficient mechanical strength and stability. In addition, other additives can achieve an ideal foam form by adjusting the speed of the entire reaction to prevent the foam from curing prematurely or over-expanding.

  4. Post-treatment phase: Finally, all ingredients work together to ensure that the foam meets the expected physical and chemical characteristics such as density, hardness and elasticity.

Through the above complex chemical processes, ZF-11 not only effectively promotes the formation and development of foams, but also significantly reduces the generation of strong odors and harmful by-products commonly found in traditional catalysts, reflecting its dual advantages in environmental protection and performance.

Performance parameters and comparison analysis of ZF-11 catalyst

The low-odor foamed polyurethane catalyst ZF-11 stands out in the market with its excellent performance parameters, especially in terms of reactive activity, odor control and cost-effectiveness. The following will compare the performance parameters of ZF-11 with other common polyurethane catalysts in detail to help readers understand their advantages more clearly.

Performance Parameter Table

parameters ZF-11 Common amine catalysts Common Metal Catalysts
Reactive activity (unit: seconds) 5-10 10-15 15-20
GoodFlavor Level (Unit: ppm) <1 5-10 3-8
VOC emissions (unit: g/m³) <0.5 2-5 1-4
Cost (unit: yuan/kg) Medium High Low

Reactive activity

Reactive activity is an important indicator for measuring the efficacy of catalysts. ZF-11 is able to start and complete most reactions in just 5 to 10 seconds, with significantly improved efficiency compared to traditional amine catalysts (usually 10 to 15 seconds) and metal catalysts (usually 15 to 20 seconds). This means that using ZF-11 can greatly shorten the production cycle and improve the overall efficiency of the production line.

Odor Control

Odor control is one of the key factors in evaluating the environmental performance of catalysts. The odor grade of ZF-11 is lower than 1ppm, which is much lower than that of ordinary amine catalysts (5-10ppm) and metal catalysts (3-8ppm). This extremely low odor level not only improves the working environment, but also reduces the potential threat to workers’ health, and meets the requirements of modern green chemicals.

VOC emissions

The emissions of volatile organic compounds (VOCs) are directly related to the environmental properties of the product. The VOC emissions of ZF-11 are less than 0.5 g/m³, compared with the VOC emissions of amine catalysts typically range between 2 and 5 g/m³ while metal catalysts range between 1 and 4 g/m³. Lower VOC emissions make ZF-11 an ideal choice for pursuing environmentally friendly production.

Cost-effective

Although the initial cost of ZF-11 may be slightly higher than that of some base metal catalysts, its overall cost-effectiveness is considerable given the improved production efficiency brought by its high reactivity and the long-term environmental benefits of low odor and VOC emissions. For enterprises that focus on sustainable development, choosing ZF-11 can not only save operating costs, but also enhance brand image.

From the above comparison analysis, it can be seen that the low-odor foamed polyurethane catalyst ZF-11 has performed excellently in reactive activity, odor control and VOC emissions with its excellent performance parameters. It is a highly efficient and environmentally friendly catalyst worth recommending.
