Technical profile of Vinyltrimethoxysilane, a high-purity raw chemical material supplied by Triveni Chemicals for industrial manufacturing and laboratory synthesis.


Vinyltrimethoxysilane is an organosilane coupling agent with the chemical formula C5H12O3Si and molecular weight 148.24 g/mol. It appears as a clear, colorless liquid with a mild ester-like odor. It is moisture-sensitive and hydrolyzes in the presence of water to form silanols and methanol. It is soluble in organic solvents and stable under dry storage conditions.
In terms of uses and applications, Vinyltrimethoxysilane is widely used in the adhesives, sealants, coatings, and polymer industries as a coupling agent and crosslinking promoter. It improves adhesion between organic polymers and inorganic surfaces such as glass, silica, and metals. It is commonly used in silane-crosslinked polyethylene (PEX) cables and pipes to enhance thermal and mechanical properties. In the rubber industry, it improves reinforcement and durability. It is also applied in construction chemicals, waterproofing systems, and composite materials. Additionally, it is used in specialty coatings and surface modification processes to enhance chemical resistance and bonding performance.
