Vinyltriethoxysilane (VTES) Moisture Scavenger
Vinyltriethoxysilane (VTES) is a reactive silane used as a moisture scavenger in moisture-sensitive adhesive and sealant formulations, particularly one-component polyurethane and silane-modified polymer (SMP/MS) systems. It reacts rapidly and preferentially with trace water, protecting the reactive NCO or silyl groups from premature cure during storage. VTES also acts as a crosslinker and adhesion promoter in silicone and polyolefin systems.
