3-(Triethoxysilyl)propylisocyanate: An Overview of Its Properties and Uses
3-(Triethoxysilyl)propylisocyanate, also known as 3-Isocyanatopropyltrimethoxysilane, is a versatile silane coupling agent widely used in the chemical industry. This product is manufactured and supplied by INNO Specialty Chemicals, a leading chemical company based in China.
Properties of 3-(Triethoxysilyl)propylisocyanate
The molecular formula of 3-(Triethoxysilyl)propylisocyanate is C9H19NO4Si, and its molecular weight is 241.34 g/mol. This product appears as a colorless to pale yellow liquid with a pungent odor. It has a boiling point of 190°C and a melting point of -42°C. Its density is 1.042 g/mL at 25°C, and it has a refractive index of 1.439.
3-(Triethoxysilyl)propylisocyanate is highly reactive and has a low viscosity, making it easy to handle and mix with other chemicals. It is soluble in organic solvents such as ethanol, methanol, and toluene, but it is insoluble in water.
Uses of 3-(Triethoxysilyl)propylisocyanate
As a silane coupling agent, 3-(Triethoxysilyl)propylisocyanate is used to improve the adhesion and compatibility between organic and inorganic materials. It is commonly used in the production of adhesives, coatings, and sealants, as well as in the treatment of mineral fillers and reinforcing agents.
Specifically, 3-(Triethoxysilyl)propylisocyanate can be used to:
1. Enhance the bonding strength between rubber and inorganic fillers, such as silica, clay, and carbon black. This improves the mechanical properties of rubber products, such as tires, hoses, and seals.
2. Improve the adhesion between coatings and surfaces, such as metal, glass, and ceramics. This increases the durability and corrosion resistance of the coatings.
3. Modify the surface properties of mineral fillers, such as calcium carbonate, talc, and mica. This improves their dispersibility and compatibility with polymers, resulting in better mechanical and rheological properties of the composites.
4. Increase the hydrophobicity of surfaces, such as concrete, stone, and wood. This improves their water repellency and durability, especially in outdoor applications.
In addition, 3-(Triethoxysilyl)propylisocyanate can be used as a building block in the synthesis of various organic and inorganic compounds, such as urethane, amide, and carbamate derivatives. These compounds have a wide range of applications, such as in the production of polyurethane foams, elastomers, and coatings.
Safety Considerations
3-(Triethoxysilyl)propylisocyanate is a hazardous substance and should be handled with care. It can cause skin and eye irritation, as well as respiratory and digestive problems if ingested or inhaled. Therefore, it is recommended to wear protective gloves, goggles, and masks when handling this product, and to work in a well-ventilated area.
Conclusion
3-(Triethoxysilyl)propylisocyanate is a valuable silane coupling agent that plays an important role in many industrial applications. Its versatility and reactivity make it a preferred choice for improving the adhesion and compatibility of various materials. However, its hazardous nature requires proper handling and safety measures to avoid any health risks. As a leading manufacturer and supplier of 3-(Triethoxysilyl)propylisocyanate, INNO Specialty Chemicals is committed to providing high-quality and reliable products to meet the needs of its customers.
