We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide , Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:
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.
Tetrapropoxysilane is a colorless transparent liquid. Used as cross-linking agent for room temperature vulcanizing rubber. Meanwhile, it is an important silicone coupling agent, crosslinking agent, widely used in the treatment of paints, coatings, silicone rubber and inorganic materials.
