The development trend of new waterproof materials: the application prospects of composite tertiary amine catalyst SA-800
Introduction: From being unobstructed to being solid
In modern society, waterproofing materials have become an indispensable part of construction, industry and daily life. Just imagine, if the house does not have a reliable waterproof layer, a heavy rain may turn the living room into a swimming pool; if the waterproofing system of the bridge or tunnel fails, the consequences will be even more unimaginable. Therefore, the importance of waterproofing materials is self-evident. However, with the advancement of technology and the upgrading of demand, traditional waterproof materials can no longer meet the performance, environmental protection and sustainability requirements of modern engineering. Therefore, new waterproof materials emerged and became the new favorite for the development of the industry.
In this waterproofing technology revolution, the role of catalysts cannot be underestimated. They are like “commanders” in chemical reactions, which can accurately regulate the reaction rate and direction, thereby improving the performance of the material. Among many catalysts, the composite tertiary amine catalyst SA-800 is gradually becoming a star product in the field of waterproof materials due to its unique properties and wide application potential. This article will start from the basic characteristics of SA-800, combine domestic and foreign literature to deeply explore its application prospects in waterproof materials, and look forward to future development directions.
So, what exactly is the composite tertiary amine catalyst SA-800? How does it change the future of waterproof materials? Let us unveil its mystery together!
Chapter 1: Basic characteristics of composite tertiary amine catalyst SA-800
1.1 Definition and Structure
Composite tertiary amine catalyst SA-800 is a highly efficient catalyst composed of a variety of tertiary amine compounds through a special process. It has the following characteristics:
- Multi-component synergistic effect: SA-800 is not a single-component catalyst, but is made of a mixture of multiple tertiary amine compounds in a specific proportion. This multicomponent design allows it to exhibit excellent catalytic properties under different conditions.
- High activity and selectivity: As a strong alkaline catalyst, SA-800 can significantly accelerate the curing reaction of materials such as polyurethane (PU), and can also effectively control the occurrence of side reactions and ensure the stability of the performance of the final product.
1.2 Chemical Properties
| Properties | parameter value |
|---|---|
| Appearance | Light yellow transparent liquid |
| Density | 1.05 g/cm³ |
| Viscosity | 50~70 mPa·s |
| Activity content | ?98% |
| pH value | 10.5~11.5 |
These parameters show that the SA-800 is not only easy to process and store, but also exhibits extremely high stability during use. For example, its high density and moderate viscosity make it easy to mix with other raw materials without delamination or precipitation.
1.3 Working principle
The main function of SA-800 is to promote the reaction between isocyanate (NCO) and polyol (OH) to form polyurethane (PU). This process can be vividly compared to “building blocks” – isocyanates and polyols are like blocks of blocks, while SA-800 is like a pair of clever hands, quickly and accurately splicing these blocks together to form a solid molecular structure.
In addition, SA-800 can also adjust the reaction rate to avoid bubble problems caused by excessive reaction. It’s like an experienced chef who accurately grasps the heat while cooking to ensure that every dish is full of color, fragrance and flavor.
Chapter 2: Advantages of SA-800 in waterproof materials
2.1 Improve waterproofing performance
The core goal of waterproofing materials is to prevent moisture penetration, and the SA-800 performs particularly well in this regard. By promoting the crosslinking reaction of polyurethane, it can form a dense three-dimensional network structure, thereby greatly improving the material’s impermeability and durability. In a simple sentence, it is “let the water have no holes to enter.”
| Material Type | Before adding SA-800 | Add SA-800 |
|---|---|---|
| Polyurethane coating | Permeability: 0.3 mm | Permeability: 0.05 mm |
| Polyurethane Sealant | Tension strength: 4 MPa | Tension strength: 6 MPa |
From the above table, we can see that after adding SA-800, all performance indicators of the material have been significantly improved.
2.2 Improve construction performance
In addition to improving waterproofing performance, the SA-800 can also improve the construction performance of the material. For example, it can extend the pot life of the material and make the applicationWorkers have more time to operate; at the same time, they can shorten the curing time and speed up the construction progress. This “long-term and short” feature is like an excellent project manager, which not only ensures the quality of the project, but also improves efficiency.
2.3 Environmental protection and safety
With the increasing global attention to environmental protection, green chemical industry has become an important direction for the development of the industry. As a catalyst for low volatile organic compounds (VOCs), SA-800 is in line with this trend. Compared with traditional organic tin catalysts, it is not only less toxic, but also does not release harmful gases, making it more friendly to human health and the environment.
Chapter 3: Current status and development trends of domestic and foreign research
3.1 Domestic research progress
In recent years, my country has made great progress in the field of waterproof materials, especially in the research and development of composite tertiary amine catalysts. For example, a research team from a well-known university successfully developed a new catalyst by optimizing the molecular structure of SA-800, whose catalytic efficiency is more than 30% higher than that of traditional products. This research result has applied for a national invention patent and has been practically applied in multiple engineering projects.
3.2 Foreign research trends
In foreign countries, SA-800 and its similar products have also received widespread attention. A chemical company in the United States has further improved the dispersion and stability of the catalyst by introducing nanotechnology. They found that the nano-treated SA-800 not only has better catalytic effect, but also significantly improves the mechanical properties of the materials.

Chapter 4: Case Analysis and Practical Application
In order to better illustrate the application value of SA-800, let’s take a look at a few practical cases.
4.1 High-speed rail tunnel waterproofing project
A high-speed rail tunnel project uses polyurethane waterproof coating containing SA-800. After long-term monitoring, the results show that the paint has better anti-seepage performance than traditional products, and there are no quality problems during the construction process. In addition, due to its environmentally friendly characteristics, the working environment of construction workers has also been significantly improved.
4.2 Roof waterproofing renovation
