Bis[3-(triethoxysilyl)propyl]amine CAS No:13497-18-2 C18H43NO6Si2

Main Applications

1.‌Coupling and Bonding Enhancement‌: Used in coatings, inks, adhesives, and sealants such as polyurethane, epoxy, silicone, and acrylic to significantly improve adhesion, water resistance, and weather resistance between inorganic materials (glass, metal, fillers) and organic resins.

2.‌Composite Reinforcement‌: In glass fiber, resin-sand casting, and abrasives, it improves the bond strength between the resin and fillers, enhancing the mechanical strength and cross-linking density of composites.

3.Curing and Modification: Serves as an amine curing agent for epoxy resins; used for isocyanate-capping modification to prepare one-component, primer-free polyurethane adhesives, thereby reducing free isocyanate content.

4.Dispersion Improvement: Promotes the dispersion and binding of pigments and fillers in the resin phase.‌‌
