Hexamethyldisilane (hexamethyldisilicone, abbreviated as LMDMS) is an organosilicon compound
Appearance: colorless liquid, low viscosity liquid at room temperature.
Stability: good thermal and chemical stability, can be used in a wide temperature range.
Volatility: with low vapor pressure and volatility, it can be used to prepare hardened silica gel and other polymer materials.
Uses:
Adhesives: As a basic component of adhesives, it can be used for bonding glass, ceramics, metals and other materials.
Coatings: Used to prepare special coatings with excellent heat resistance and weather resistance.
Surface modifiers: can be used to improve the surface wettability and adhesion of materials.
Waterproofing agent: Used as a waterproofing agent to enhance the waterproof performance of materials.
Preparation method:
Peroxosilicate synthesis method: by reacting inorganic silicate and methyl alcohol, hexamethyldisilane is generated.
Safety information:
Hexamethyldisilane is a flammable liquid and should be kept away from sources of ignition and high temperature environments.
When contacting hexamethyldisilane, avoid direct contact with skin and eyes to avoid irritation or burns.
Good ventilation should be observed during operation to prevent the accumulation of hexamethyldisilane vapors leading to high concentrations in the air.
Store away from oxidizing agents and strong acids and alkalis to avoid unsafe reactions.
