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.
