What is Glycidoxypropylmethyldiethoxysilane?
Glycidoxypropylmethyldiethoxysilane (CAS 2897-60-1), also known as 3-Glycidoxypropylmethyldiethoxysilane, is an epoxy-functional organosilane that bonds organic polymer matrices to inorganic substrates.
Where is Glycidoxypropylmethyldiethoxysilane used?
- Electronics: adhesion promoter between epoxy encapsulants and semiconductor substrates, reducing delamination in printed circuit boards and chip packaging
- Coatings: wet adhesion and chemical resistance on glass, metal and mineral surfaces
- Adhesives and sealants: crosslinking agent strengthening bonds between silicone or epoxy systems and substrates such as aluminum and ceramics
- Composites: sizing or primer component improving interfacial strength between glass fibers and polymer resins
- It acts as a coupling agent, crosslinker and surface modifier.
Good to know: Buyers should confirm purity specifications and moisture content tolerances with suppliers, as these affect shelf life and reactivity.
Commercial specifications
- Packaging from kilogram quantities to bulk drums
- Technical and high-purity grades
