Bifunctional silane coupling agent combining epoxy and alkoxysilane reactivity for enhanced interfacial adhesion.
Contains a flexible propyl spacer between epoxy and silane moieties, improving compatibility with organic polymers and reducing brittleness.
Diethoxy substitution provides balanced hydrolysis rate—sufficient stability for formulation handling and controlled reactivity during curing.
Enables covalent bonding to both inorganic substrates (e.g., glass, metals, fillers) and organic matrices (e.g., epoxies, acrylics, polyurethanes).
Low volatility and favorable storage stability under recommended conditions (cool, dry, nitrogen-blanketed).
Epoxy resin composites for aerospace and electrical insulation requiring high dielectric strength and moisture resistance.
Surface treatment of silica, alumina, and calcium carbonate fillers in high-performance rubber and thermoset compounds.
Adhesion promoters in structural adhesives and sealants for metal-to-polymer bonding in automotive assemblies.
Functional additive in UV-curable and thermally cured epoxy-acrylate hybrid coatings for improved substrate wetting and corrosion protection.
Primer component for glass fiber-reinforced polymer (GFRP) laminates in wind turbine blades and marine composites.
