QUICK LINKS

Triphenyl(vinyl)silane is a silane coupling agent. It acts as a molecular bridge between organic and inorganic materials, facilitating adhesion and improving the mechanical properties of composite materials. Triphenyl(Vinyl)Silane is capable of forming covalent bonds with both organic and inorganic surfaces, enhancing the compatibility and interfacial adhesion between different materials. At the molecular level, triphenyl(vinyl)silane undergoes a condensation reaction with hydroxyl groups on the surface of inorganic materials, forming strong siloxane bonds. This mechanism allows for the creation of durable and stable interfaces between organic polymers and inorganic fillers, leading to improved mechanical strength and thermal stability in composite materials. Triphenyl(vinyl)silane can also modify the surface properties of inorganic materials, promoting better dispersion and wetting of fillers within polymer matrices.
