Name: Domestic D-20 Methyltrimethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic D-20 Methyltrimethoxysilane

High purity methyltrimethoxysilane with consistent reactivity for reliable silanization performance.
Low moisture sensitivity compared to alternative alkoxysilanes, enabling improved handling and shelf stability.
Excellent compatibility with organic polymers, solvents, and inorganic fillers in hybrid formulation systems.
Hydrolyzes rapidly under mild acidic or neutral conditions to generate reactive silanol intermediates.
Versatile coupling functionality for enhancing adhesion between organic resins and glass, metal, or mineral substrates.

Typical Applications Of Domestic D-20 Methyltrimethoxysilane

Adhesion promoter in silicone-modified acrylic and polyurethane coatings.
Coupling agent in RTV silicone sealants and liquid silicone rubber (LSR) formulations.
Surface modifier for silica nanoparticles and fumed silica in composite materials.
Crosslinker in moisture-curable sealants and adhesives for construction and automotive assembly.
Functional additive in sol-gel derived hybrid coatings for corrosion protection and anti-fouling surfaces.
