Name: Domestic D-150 Methyltriethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic D-150 Methyltriethoxysilane

High-purity methyltriethoxysilane with ≥98.5% assay, ensuring consistent reactivity in silane coupling processes.
Low water content (<0.1%), minimizing premature hydrolysis and extending shelf life under sealed storage.
Excellent compatibility with organic polymers, solvents, and inorganic fillers—ideal for hybrid material formulation.
Controlled ethoxy group reactivity enables tunable condensation kinetics for optimized crosslinking in coatings and adhesives.
Non-corrosive to common stainless steel and glass-lined equipment, supporting safe industrial handling and processing.

Typical Applications Of Domestic D-150 Methyltriethoxysilane

Surface modification of silica, glass, and metal oxides in high-performance composites and masterbatches.
Coupling agent in silicone-modified acrylic and polyurethane coatings for enhanced substrate adhesion and weather resistance.
Hybrid precursor in sol-gel synthesis of ORMOSILs (organically modified silicates) for optical and protective thin films.
Moisture-scavenging additive in moisture-sensitive polymer systems such as epoxy encapsulants and RTV silicones.
Functionalization reagent for silica nanoparticles used in biomedical diagnostics and controlled-release carriers.
