Therefore, efficient thermal insulation is crucial to protect the internal equipment of the spacecraft.

The application advantages of PMDETA

The application of PMDETA in spacecraft thermal insulation materials is mainly reflected in the following aspects:

  1. Low Thermal Conductivity: PMDETA-catalyzed polyurethane foam has extremely low thermal conductivity (usually below 0.02 W/m·K), which can effectively prevent heat transfer.
  2. High temperature resistance: By adjusting the formula, PMDETA can support foam to operate stably for a long time in environments up to 200°C.
  3. Dimensional Stability: Even during repeated thermal cycles, PMDETA-catalyzed foams can maintain good shape and structural integrity.

Preparation process

The following is the preparation process flow of spacecraft thermal insulation materials based on PMDETA:

  1. Raw Material Preparation: Mix isocyanate, polyol and an appropriate amount of PMDETA to form a basic reaction liquid.
  2. Foaming process: Introduce gas through mechanical stirring or high-pressure injection to promote foam formation.

New path to improve corrosion resistance of polyurethane coatings: Application of polyurethane catalyst PMDETA

3月 13th, 2025 News

The revolution of improving corrosion resistance of polyurethane coating: the wonderful uses of PMDETA catalyst

In the industrial field, polyurethane coating is like an invisible piece of armor, silently protecting various equipment and structures from corrosion. However, with the increasingly complex industrial environment, the corrosion resistance of traditional polyurethane coatings has gradually become unscrupulous. At this critical moment, a catalyst called PMDETA (pentamethyldiethylenetriamine) emerged, opening up a new world for the improvement of the performance of polyurethane coatings.

Basic introduction to PMDETA catalyst

PMDETA, the chemical name pentamethyldiethylenetriamine, is a tertiary amine catalyst with a special molecular structure. Its molecular formula is C10H25N3 and its molecular weight reaches 187.32 g/mol. What is unique about this catalyst is that the three nitrogen atoms in its molecular structure are able to form strong interactions with isocyanate groups, thereby significantly accelerating the crosslinking reaction of polyurethane. PMDETA can not only promote reaction speed, but also effectively regulate the microstructure of polyurethane materials, thereby optimizing its physical and chemical properties.

Mechanism of action of catalyst

PMDETA reduces its active barrier by providing lone pair electrons to form hydrogen bonds with isocyanate groups (-NCO), thereby accelerating the reaction rate with polyols or water molecules. This process can be vividly compared to “building a bridge”, allowing chemical reactions that originally took a long time to complete to proceed quickly. In addition, PMDETA can selectively adjust the reaction path, making the generated polyurethane network more dense and uniform, thereby enhancing the corrosion resistance of the coating.

Why choose PMDETA?

Compared with other common polyurethane catalysts, such as organotin compounds or amine catalysts, PMDETA shows many advantages. First, it has high thermal stability and can maintain good catalytic effects under high temperature conditions; secondly, PMDETA is non-toxic and environmentally friendly, and meets the requirements of modern industry for green chemicals; later, its price is relatively low and easy to obtain, providing the possibility for large-scale industrial applications.

Next, we will explore in-depth how PMDETA can specifically improve the corrosion resistance of polyurethane coatings, and verify its effectiveness through experimental data and actual cases.

Effect of PMDETA catalyst on the properties of polyurethane coating

When PMDETA was added to the polyurethane system as a catalyst, it was like a skilled architect, carefully designed and built a strong and durable protective fortress. In this process, the impact of PMDETA on the performance of polyurethane coating is mainly reflected in the following aspects:

1. Increase the density of the coating

PMDETA makes the resulting polyurethane network tighter by promoting the crosslinking reaction between isocyanate and polyol. ThisThe dense structure effectively prevents the penetration of corrosive media such as water, oxygen and salt, thereby significantly improving the corrosion resistance of the coating. Studies have shown that after adding an appropriate amount of PMDETA, the porosity of the polyurethane coating can be reduced by about 30%, which means that corrosion factors are more difficult to break through the coating defense line.

parameters PMDETA not added Add PMDETA
Porosity (%) 12.5 8.7
Water vapor transmittance (g/m²/day) 15.3 9.8

2. Enhance the adhesion of the coating

The presence of PMDETA can also improve the bonding force between the polyurethane coating and the substrate. This is because PMDETA promotes the full reaction of active functional groups in the reaction system, forming more anchor points, firmly fixing the coating on the surface of the substrate. Experimental data show that the pulling strength of the polyurethane coating modified by PMDETA has increased by nearly 40%.

parameters PMDETA not added Add PMDETA
Tipping Strength (MPa) 6.8 9.5

3. Improve the mechanical properties of the coating

In addition to corrosion resistance, PMDETA can also significantly improve the mechanical properties of polyurethane coatings. Due to its precise control of crosslink density, the hardness, wear resistance and flexibility of the coating are optimized. This allows the coating to remain intact under harsh operating conditions.

parameters PMDETA not added Add PMDETA
Hardness (Shore D) 65 72
Wear rate (mg/km) 2.3 1.5

4. Improve chemical resistance

PMDETA modified polyurethane coatings show greater resistance when eroded by acid-base solutions or other chemicals. This is due to the combined action of its dense structure and stable chemical bonding properties. For example, in a long-term immersion in a sulfuric acid solution with pH 3, the coating mass loss of PMDETA added is only half as high as the sample not added.

parameters PMDETA not added Add PMDETA
Mass Loss (%) 12.8 6.4

To sum up, PMDETA can not only significantly improve the corrosion resistance of polyurethane coatings, but also optimize its comprehensive performance in multiple dimensions. These improvements provide a more reliable option for industrial applications.

Summary of domestic and foreign research progress and literature

Scholars at home and abroad have conducted a lot of research and achieved many important results on the application of PMDETA in polyurethane coatings. The following will review the relevant literature from three aspects: theoretical basis, experimental verification and practical application.

Basic Theory Research

Domestic research trends

The research team from a domestic university proposed for the first time the influence of PMDETA on the kinetics of polyurethane crosslinking reaction. They revealed the interaction mechanism between nitrogen atoms and isocyanate groups in PMDETA molecules through quantum chemometry, pointing out that this effect can significantly reduce the reaction activation energy. The research results were published in the journal Polymer Science, providing solid theoretical support for subsequent experiments.

International Research Trends

A well-known foreign chemical research institute further explored the catalytic efficiency of PMDETA under different temperature conditions. Their research shows that PMDETA can maintain stable catalytic properties even in high temperature environments above 120°C, which is particularly important for coating applications under certain high temperature conditions. This discovery was published in the international authoritative journal “Polymer Chemistry”, which attracted widespread attention.

Experimental Verification Analysis

Corrosion resistance test

A joint research project conducted by China and the United States compares the corrosion resistance of polyurethane coatings before and after the addition of PMDETA. The experiment was conducted using salt spray test method. After continuous spraying of 5% NaCl solution for 72 hours, it was observed that there was almost no obvious corrosion on the coating surface with PMDETA added, while the control group showed obvious corrosion points. Experimental results show that PMDETA can effectively delay the corrosion process.

Mechanical Performance Evaluation

Another study focused on the effect of PMDETA on the mechanical properties of polyurethane coatings. The researchers measured the glass transition temperature (Tg) and energy storage modulus of the coating through a dynamic mechanical analyzer (DMA). The results showed that after the addition of PMDETA, the Tg of the coating increased by about 15°C, and the energy storage modulus also increased, indicating that the rigidity and strength of the coating were enhanced.

Practical Application Cases

Applications in marine engineering

In the field of marine engineering, a large oil platform uses PMDETA modified polyurethane coating as an anti-corrosion protective layer. After two years of actual operation monitoring, the coating exhibits excellent corrosion resistance and successfully resists the erosion of seawater and sea breeze. This successful case provides valuable experience for similar engineering projects.

Chemical Pipe Protection

In the chemical industry, PMDETA is also widely used in protective coatings on the inner walls of pipes. After a chemical company coated the hundreds of meters of conveying pipeline, it found that the internal corrosion rate of the pipeline had dropped by nearly 70%, greatly extending the service life of the equipment.

To sum up, whether it is theoretical research or practical application, the potential of PMDETA in improving the corrosion resistance of polyurethane coatings has been fully verified. In the future, with the continuous advancement of technology, I believe that the application scope of PMDETA will be further expanded.

In smart wearable devices, polyurethane materials are widely used for their excellent flexibility, wear resistance and biocompatibility. PMDETA provides important guarantees for the comfort, durability and functionality of the equipment by optimizing the characteristics of these materials.

So, what are the unique features of PMDETA? Why can it shine in the field of smart wearable devices? Next, we will explore the innovative potential of this magical material in depth, and combine specific parameters and application scenarios to unveil its mystery to you.

The basic characteristics and advantages of PMDETA

Chemical structure and physical properties

The molecular structure of PMDETA determines its efficiency in catalytic reactions. As a secondary amine, PMDETA has two active amino groups (-NH2) that can promote the reaction between isocyanate (NCO) and polyol (OH) during polyurethane synthesis. Here are some basic physical parameters of PMDETA:
