Silane coupling agent

Silane Coupling Agents are bifunctional organosilicon compounds with the general formula Y-R-SiX3. In this structure, the X group (typically alkoxy) hydrolyzes to form silanols that bond to inorganic surfaces, while the Y organofunctional group (e.g., amino, epoxy, vinyl) bonds with organic polymers. This unique dual reactivity creates a stable bridge between organic and inorganic materials, significantly improving adhesion, composite strength, and durability.
