Features and uses :
Isocyanate propyltriethoxysilane (IPTS) is used in the crosslinking of ethylene-vinyl acetate copolymer, chlorinated polyethylene, ethylene-acrylic acid-ethyl acetate copolymer. Isocyanate propyltriethoxysilane (IPTS) is suitable for polyacid resin, epoxy resin, phenolic resin, melamine formaldehyde resin, nylon, polysulfone and other FRP materials. FRP treated with isocyanate propyltriethoxysilane (IPTS) can be widely used in the manufacture of mechanical parts, construction materials, pressure vessels and reinforcement materials for some special purposes . Isocyanate propyltriethoxysilane (IPTS) is also used as a tackifier for rubber and metal bonding, and as a reinforcement for self-hardening resin sand cores in the foundry industry. The practical fillers for this product are glass fiber , glass cloth, glass Microbeads, white carbon black, talc, clay, mica, fly ash, clay composite silica as a rubber processing aid, used to couple a variety of halogenated rubber, such as: neoprene, chlorinated butyl rubber, Chlorohydrin rubber, chlorosulfonated polyethylene, made into light-colored products to improve various physical and mechanical properties. The isocyanate propyltriethoxysilane (IPTS) molecule contains two different active genes—isocyanate and ethoxy, which are used to couple organic molecules and inorganic fillers, enhance their adhesion, and improve the mechanical, electrical, and mechanical properties of the product. Water resistance, anti-aging and other properties. Commonly used in fiberglass, casting , textile additives, insulating materials, adhesives and other industries. Isocyanate propyltriethoxysilane (IPTS) The polymers suitable for this coupling agent include epoxy, phenolic, melamine, nylon, polyvinyl chloride, polyacrylic acid, polyurethane, polysulfide rubber, nitrile rubber, etc.
Isocyanatepropyltriethoxysilane (IPTS) is an excellent adhesion promoter for polyurethane, epoxy, nitrile, phenolic adhesives and sealants, improving pigment dispersion and improving adhesion to glass, aluminum, ferrous metals Excellent adhesion, also suitable for polyurethane, epoxy and acrylic latex paints .
