Description

Description

Methyltrichlorosilane is used in production of methyl silicone resins, its vapor reacts with water on surfaces to give a thin layer of methylpolysiloxane which make it a water-repellent film. A combination of methyltrichlorosilane and sodium iodide can be used to cleave carbon-oxygen bonds such as methyl ethers. It is used as a precursor for forming various cross-linked siloxane polymers. Trichloromethylsilane is the starting material for the production of pure silicon for manufacture of semiconductors and optical fibers.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
