General Description

Hexamethoxydisilane is a colorless, clear liquid chemical compound with the molecular formula Si2C6H18O6. It is a type of silane compound, which is used as a crosslinking agent in the manufacturing of silicone elastomers and polymers. Hexamethoxydisilane is also utilized as a surface modifying agent in the production of hydrophobic coatings and in the preparation of organosilicon compounds. This chemical is flammable and should be handled with caution, as it can release harmful fumes and vapors when exposed to high temperatures. Additionally, it is essential to store Hexamethoxydisilane in a cool, well-ventilated area and avoid contact with skin and eyes to prevent irritation or damage.
