What is 3-Aminopropyltriethoxysilane CAS 919-30-2?

Widely used coupling agent has active groups at one end of its structure that can react with epoxy, phenolic, polyester and other synthetic resin molecules, such as amino, vinyl, etc. At the other end are alkoxy groups (such as methoxy, ethoxy, etc.) or chlorine atoms connected with silicon. In the presence of water in aqueous solution or air, these groups can be hydrolyzed to react with hydroxyl groups on the surface of glass, minerals, and inorganic fillers to generate reactive silanol.

Application

1.Applicable polymers include epoxy, phenolic, melamine, nylon, polyvinyl chloride, polyacrylic acid, polyurethane, polysulfide rubber, nitrile rubber, etc
2.It is used as a silane coupling agent for glass fiber treatment agent and dental bonding agent, as well as for thermoplastic and thermosetting resins such as mineral filled phenolic, polyester, epoxy, PBT, polyamide and carbonate,
3.It is an excellent adhesion accelerator and can be used for polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials. It can improve the dispersion of pigments and improve the adhesion to glass, aluminum and iron metals. It is also suitable for polyurethane, epoxy and acrylic latex coatings. In resin sand casting, it can enhance the adhesion of resin silica sand and improve the strength and moisture resistance of molding sand.
