High-purity vinyltrimethoxysilane (VTMS) with ≥97.0% assay for consistent coupling performance.
Low volatility and excellent hydrolytic stability in anhydrous storage conditions.
Enables strong covalent bonding between inorganic fillers (e.g., silica, glass) and organic polymer matrices.
Facilitates improved dispersion of fillers and reduced viscosity in unsaturated polyester and vinyl ester resins.
Compatible with free-radical curing systems, supporting efficient crosslinking during composite processing.
Fiber-reinforced polymer (FRP) composites for wind turbine blades and automotive structural parts.
Surface treatment of mineral fillers in high-performance rubber compounds (e.g., tire treads).
Adhesion promotion in glass-fiber sizing formulations for thermoset and thermoplastic composites.
Functional additive in silicone-modified acrylic emulsions for architectural coatings.
