Triethoxyvinylsilane(TEVS) is a silane coupling agent and an adhesion promoter that can be used for cross-linking and for providing an insulating layer with good mechanical and thermal properties.
Triethoxyvinylsilane, also known as vinyltriethoxysilane, is a vinyl-functional silane that may be used to improve the bond between glass fiber or mineral fillers and resins that are reactive toward the vinyl group. It is also employed to functionalize resins via free radical mechanisms - copolymerization or grafting - and to modify surfaces.

CAS 78-08-0 Properties
Silane OSi HIOSil VTEO, as a co-monomer in polymers, can significantly improve wet scrub and abrasion resistance thanks to crosslinking and better adhesion to the substrate. Silane-modified thermoplastics obtained by grafting with Silane OSi HIOSil VTEO can be processed further using standard techniques. On exposure to moisture, the silyl groups condense and function as crosslinking or adhesion points.
By treating fillers with Silane OSi HIOSil VTEO, mineral-filled polymers can be obtained that exhibit improved mechanical and electrical properties.
In addition, the particles are rendered strongly water-repellent, which results in improved filler dispersibility and thus facilitates processing. Organic surface coatings will adhere more strongly to inorganic substrates treated with Silane OSi HIOSil VTEO. As a result, these coatings demonstrate markedly greater scratch resistance and resistance to chemicals.
