Methyltrichlorosilane

Product Overview

Methyltrichlorosilane is a highly reactive organosilicon compound widely employed in the synthesis of specialty silicon-based materials. With a molecular formula of CH₃Cl₃Si and a molecular weight of 149.48 g/mol, this colorless, clear liquid serves as a critical building block in the production of silane crosslinkers, coupling agents, and functional siloxanes. Its high reactivity with moisture enables rapid hydrolysis, making it ideal for surface modification and protective coating applications.

Specifications

Industrial Applications

Methyltrichlorosilane is extensively utilized across multiple high-performance industries due to its versatile chemical functionality:

• As a key precursor in the manufacture of silane coupling agents that enhance adhesion between organic polymers and inorganic substrates.
• In hydrophobic treatment formulations for glass, minerals, and textiles to impart water-repellent properties.
• As a pyrolytic precursor for silicon-carbon (Si-C) ceramic coatings used in aerospace and high-temperature environments.
• In the synthesis of tailored siloxane resins for sealants, coatings, and electronic encapsulants.

Due to its moisture sensitivity and flammability, Methyltrichlorosilane must be handled under inert atmosphere and stored in a cool, well-ventilated area away from water and ignition sources. Standard packaging is 200 kg drums, with custom options available upon request.
