Silquest A-1120, also known as N-(β-Aminoethyl)-γ-aminopropyltrimethoxysilane, is a highly versatile bifunctional organosilane. It features both primary amine and trimethoxysilyl groups, enabling it to chemically bond with a wide array of inorganic materials such as glass, metals, and various fillers, as well as organic polymers including plastics, rubbers, and resins. This clear to light yellow liquid, with a characteristic ammonia-like odor, is readily soluble in alcohol and aliphatic/aromatic hydrocarbon solvents.
It functions effectively as an adhesion promoter, surface modifier, and a rust-preventing primer. Furthermore, Silquest A-1120 serves as a critical crosslinker for both silicone and moisture-curing polymer systems. Its application significantly improves the performance and durability of composite materials, coatings, and adhesives across numerous industries.
