Organic Silicone , normally Chemical Organic Silicium which is known as Organic Silicone Chemicals, or Organosilicone Chemicals, are silicone compounds that contain Si-O bonds and have at least one organic group directly connected to a silicon atom.
Organic Silane / Silane Chemicals , or Organic Silane Chemicals the compound of silicon and hydrogen, is a general term for a range of Silicide Chemicals compounds, including silane (SiH4), ethyl silane (Si2H6) and some more advanced silicon hydrogen compounds.
Dimethyldiethoxysilane is a colorless liquid. The flash point is 75°F. Less dense than water and insoluble in water. Vapors heavier than air. It is a structural control agent for the preparation of silicone rubber, chain expander in the synthesis of silicone products and silicone oil synthesis raw material.

4) Uses:
Dimethyldiethoxysilane is a structural control agent for the preparation of silicone rubber, chain expander in the synthesis of silicone products and silicone oil synthesis raw material. It is an important raw material for the production of silicone resin, benzyl silicone oil and waterproofing agent. At the same time, it is easy to hydrolyze and can form alkali metal silicate salts with alkali metal hydroxides. And it can also be used as a crosslinking agent for room temperature vulcanized silicone rubber. Another It can be used as chemical reagent and raw material for synthesizing polymer silicone compounds.
