KBE-402 is an epoxy-functional silane coupling agent, specifically 3-Glycidoxypropyl Methyldiethoxysilane. It is designed to improve adhesion, durability, and mechanical strength in composite materials, particularly useful in epoxy and thermoset resin systems. This silane reacts more slowly than methoxy silanes, providing enhanced compatibility with various organic and inorganic substrates.
