Silicone Fluids & Oils
Vinyl-Terminated Polydimethylsiloxane (Vinyl PDMS)
CAS 68951-99-5
The reactive backbone of platinum-cure silicone rubber, built to crosslink through its terminal vinyl groups. It serves as the base polymer in addition-cure (hydrosilylation) silicone elastomer systems, reacting with hydride crosslinkers under platinum catalysis.

Silanes & Organosilanes
Vinyltriethoxysilane (VTES)
CAS 78-08-0
A bifunctional silane that chemically bridges mineral fillers and polymer matrices. It acts as a coupling agent between inorganic fillers and polymers, functioning as an adhesion promoter, crosslinker, and surface modifier, and is used in the production of general-purpose polymers.

Silanes & Organosilanes
Vinyltrimethoxysilane (VTMS)
CAS 2768-02-7
A fast-hydrolyzing vinyl silane for coupling and moisture-cure crosslinking. Its hydrolyzable methoxy groups bond inorganic surfaces while the vinyl group reacts with polymers, making it an adhesion promoter and crosslinker for filled and moisture-curable polymer systems.

Silanes & Organosilanes
Vinyltris(2-Methoxyethoxy)Silane
CAS 1067-53-4
A vinyl silane whose methoxyethoxy leaving groups tune hydrolysis for coupling and crosslinking. It is documented as an adhesion/cohesion promoter and functions as a silane coupling agent linking inorganic fillers to polymer matrices.
