3-aminopropyltriethoxysilane / kh-550 cas 919-30-2

Silane coupling agent.
Fiber / Composites: Surface treatment agents for glass fiber; enhance the bonding strength between glass fiber and resins (epoxy, phenolic, polyester), thereby improving product strength, water resistance, and aging resistance.
Adhesives and Sealants: Adhesion promoters for epoxy resins, polyurethanes, acrylic adhesives, and silicone sealants; improve bond strength to metal, glass, ceramics, and plastics, while enhancing water and temperature resistance.
Coatings and Inks: Adhesion promoters and pigment dispersants; improve paint film adhesion to metal and inorganic substrates, and enhance corrosion and scrub resistance.
Rubber and Plastics: Surface modifiers for inorganic fillers (talc, calcium carbonate, silica, aluminum hydroxide); improve filler dispersion within rubber and plastic systems, enhance mechanical properties, and reduce viscosity.
Inorganic Materials / Ceramics: Modifiers for inorganic powders such as ceramics, abrasives, mica, and quartz powder; improve compatibility between powders and organic systems; additives for ceramic glazes.
Metal Surface Treatment: Metal anti-rust and primer treatments; form protective films to enhance coating adhesion and corrosion resistance.
Other Fields: Resin modification; organic synthesis intermediates; textile waterproofing and color-fixing agents; oilfield chemical additives.
