Overview
Glycidoxypropylmethyldiethoxysilane (CAS 2897-60-1 ), also known as 3-Glycidoxypropylmethyldiethoxysilane, is an epoxy-functional organosilane used to bond organic polymer matrices to inorganic substrates.
It acts as a coupling agent, crosslinker, and surface modifier across demanding industrial applications where adhesion durability is critical. In electronics, it improves adhesion between epoxy encapsulants and semiconductor substrates.
This reduces delamination risk in printed circuit boards and chip packaging. Coatings formulators use it to enhance wet adhesion and chemical resistance on glass, metal, and mineral surfaces for long-term protection.
In adhesives and sealants, it functions as a crosslinking agent that strengthens bonds between silicone or epoxy systems and difficult substrates including aluminum and ceramics. This ensures structural integrity.
Fiber-reinforced composites for automotive and aerospace applications rely on it as a sizing or primer component. It improves interfacial strength between glass fibers and polymer resins in high-stress environments.
The material is supplied as a clear liquid in standard packaging ranging from kilogram quantities to bulk drums. It is available in technical and high-purity grades to meet the requirements of electronics applications.
Buyers should confirm purity specifications and moisture content tolerances directly with suppliers. These parameters affect shelf life and reactivity in formulation, ensuring consistent performance in industrial processes.
