1.Widely used in fiberglass industry.
2.3-Aminopropyltriethoxysilane can improve the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides,polybutylene terephthalate and many other thermoset and thermoplastic composites. Filler wetting and dispersibility in thepolymer matrix can also be improved.
3.In shell molding, this silane can strengthen the bond between the phenolic binder and foundry sand.
4.As a phenolic resin binder additive, 3-Aminopropyltriethoxysilane can impart moisture resistance and allow recovery after compression.
5.3-Aminopropyltriethoxysilane is an excellent adhesion promoter to consider for use in many coating, adhesive, and sealant systems. With polysulfide, urethane, RTV silicones,epoxy, nitrile, and phenolic adhesives and sealants, the product can improve pigment dispersion and adhesion to glass, aluminum, steel and various other substrates.
