What is 3-Aminopropyltriethoxysilane?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 3-Aminopropyltriethoxysilane which has developed particularly rapidly in recent years. Do you know about 3-Aminopropyltriethoxysilane?
- The official answer：The silane coupling agent KH-550 was the first coupling agent to be widely used and has a history of more than 40 years so far. At one end of its structure are reactive groups that can react with epoxy, phenolic, polyester, and other types of synthetic resin molecules, such as amino and vinyl groups. The other end is connected with silicon alkoxy (such as methoxy, ethoxy, etc.) or chlorine atoms, these groups in aqueous solutions or in the presence of moisture in the air, hydrolysis to generate can react with glass, minerals, inorganic filler surface of the hydroxyl group to generate reactive silanol. Therefore, a silane-type coupling agent is commonly used in silicate-filled epoxy, phenolic, polyester resin, and other systems. In addition, it can also be used in the production of FRP to improve its mechanical strength and resistance to humid environments.
What’s the application of 3-Aminopropyltriethoxysilane?
- Aminopropyltriethoxysilane Chinese alias γ-aminopropyltriethoxysilane, CAS No. 919-30-2, colorless liquid. 3-aminopropyltriethoxysilane can be used as a glass fiber treatment agent and dental binder, silane coupling agent, applied to mineral-filled phenolic, polyester, epoxy, PBT, polyamide, carbonate, and other thermoplastic and thermosetting resins, can significantly improve, and It enhances the physical and mechanical properties such as dry and wet flexural strength, compressive strength, shear strength and wet electrical properties of plastics, and improves the wettability and dispersibility of fillers in polymers. It is used in epoxy, phenolic, melamine, nylon, polyvinyl chloride, polyacrylic acid, polyurethane, polysulphide rubber, nitrile rubber, etc. It is used as a glass fiber treatment agent and dental binder, and as a silane coupling agent in mineral-filled phenolic, polyester, epoxy, PBT, polyamide, carbonate, and other thermoplastic and thermosetting resins, and can greatly improve and enhance the dry and wet flexural strength of plastics. It also improves the wettability and dispersibility of the filler in the polymer. It is an excellent bonding promoter for polyurethane, epoxy, nitrile, phenolic adhesives, and sealing materials, improves pigment dispersion and enhances adhesion to glass, aluminum, and iron metals, and is also suitable for polyurethane, epoxy, and acrylic emulsion coatings. In resin sand casting, it can enhance the adhesion of resinous silica sand, improve the strength of the sand, and resistance to moisture. In the production of glass fiber and mineral wool, it is added to phenolic resin binders to improve the moisture resistance and increase compression resilience. In the manufacture of grinding wheels, it helps to improve the adhesion and water resistance of phenolic resin binders for abrasion-resistant self-hardening sands.
