Silane coupling agents were first developed as glass fiber treatment agents for glass fiber reinforced plastics. Because the silane coupling agent improves the adhesion between glass fiber and resin, the mechanical properties of reinforced plastics are significantly improved. With the rapid development of composite materials, the development speed of silane coupling agents in both varieties and yields is also fast. In recent years, the use of silane coupling agents to introduce specific functional groups to certain materials can improve the surface properties of materials, and obtain antistatic, mildew, deodorant, anticoagulant, and physiological inertia. beginning. Because of the development of many important applications, silane coupling agents have become an important branch of silicones.

The main application of silane coupling agent
Handle glass fiber reinforced materials
Effectively improve the wet mechanical properties and stable electrical properties of composite materials.
2. Processing of mineral powder filler
Improve the mechanical strength of composite materials, improve processing performance, and enhance wetting and dispersing properties of fillers.
3. Tackifier
Used as tackifier for epoxy, polyurethane, neoprene and other adhesives and sealants, which can greatly improve the dry adhesive of resin to glass or metal substrate, and improve the wet adhesion retention rate.
Rubber processing
Improve the dispersion of inorganic fillers in rubber, improve the physical and electrical properties of rubber and comprehensive processing technology performance.
5. Other aspects
Treat the glass surface to prevent ice on the windshield surface of airplanes and automobiles.
