Product function:

3-Aminopropyltriethoxysilane is usually used in mineral-filled phenols, polyesters, epoxy resins, PBT, polyamides, carbonates and other thermoplastic and thermosetting resins. The use of 3-Aminopropyltriethoxysilane can significantly improve and enhance the wet and wet bending of plastics strength. Improve the compressive strength, shear strength and other physical and mechanical and wet electrical properties, as well as the wettability and dispersibility of the filler in the polymer.

3-Aminopropyltriethoxysilane can be used for glass fiber treatment and dental adhesives, as well as polyurethane, epoxy resin, nitrile, phenolic adhesives and sealants to improve the dispersion of pigments and increase the adhesion to glass, aluminum, and iron metals , Also suitable for compatibility, polyurethane, epoxy resin and acrylic latex coatings.

In resin sand casting, the use of 3-Aminopropyltriethoxysilane can increase the adhesion of resin silica sand and improve the strength and moisture resistance of the sand.

In the production of glass fiber cotton and mineral wool, 3-Aminopropyltriethoxysilane is added to the phenolic resin binder to improve moisture resistance and compression elasticity.

In the manufacture of grindstones, the addition of 3-Aminopropyltriethoxysilane helps to improve the adhesion and water resistance of the wear-resistant self-curing sand phenolic resin bond.
