1. Chemical Chinese name: Polymethyltriethoxysilane
2. Chemical English name: Poly-methyltriethoxysilane
Appearance: colorless to light yellow transparent liquid
Kinematic viscosity (25℃), mm2/s 1~5 1.82
Density (25℃), g/cm3 0.920~1.020 0.967

4. Physical and chemical properties: Polymethyltriethoxysilane is an oligomer of methyltriethoxysilane with an average degree of polymerization of 2~3. It has a special fragrance and is a combustible liquid. When acid or alkali is present , It is easy to hydrolyze and condense when exposed to water. The product of hydrolysis and condensation is a high molecular compound, and finally cross-linked to form a film. Polymethyltriethoxysilane has hydrophobicity and high heat resistance.
5. Main purpose: used as waterproofing agent, isolating anti-sticking agent, release agent, defoaming agent, waterproof and anticorrosive coating, methyl block room temperature vulcanized silicone rubber.
