Name: Domestic D-101 Tetramethyl Orthosilicate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Domestic D-101 Tetramethyl Orthosilicate

High-purity tetramethyl orthosilicate (TMOS) with ≥99.5% assay, ensuring consistent reactivity in sol-gel processes.
Low water content (<0.1%), minimizing premature hydrolysis and extending shelf life under proper storage conditions.
Excellent volatility and miscibility with common organic solvents (e.g., ethanol, methanol, acetone), facilitating homogeneous precursor formulation.
Controlled hydrolysis kinetics enabling precise tuning of silica network formation in coatings and aerogel synthesis.
Domestically manufactured under ISO 9001-certified production, guaranteeing batch-to-batch reproducibility and traceability.

Typical Applications Of Domestic D-101 Tetramethyl Orthosilicate

Sol-gel derived silica antireflective and protective coatings for optical lenses and display panels.
Precursor for high-surface-area silica aerogels used in thermal insulation and catalysis support.
Crosslinking agent in silicone-modified alkyd resins for industrial maintenance coatings.
Surface modification of nanomaterials (e.g., SiO₂, TiO₂ nanoparticles) to improve dispersion stability in polymer matrices.
Intermediate in the synthesis of functionalized silanes and organosilicon specialty chemicals.
