Descripción

General description

Vinyltrimethoxysilane (VTMS) is a silane coupling agent with silicon and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.

Application

VTMS may be used to provide superhydrophobicity to different materials like TiO₂, talc, kaolin, magnesium oxide nanoparticles, ammonium phosphate, and PEDOT. It modifies the surface by capping the material and creates a protective layer that is water resistant and can be used in major coating industries.
