Low hydrogen-containing silicone oil, hydrogen-containing silicone oil is a part of hydrogen-containing group silicone oil. Because the molecule contains relatively active Si-H bonds, under the action of catalysts, it can react with other chemical substances containing double bonds, hydroxyl groups and other active groups. , generate silicone products with various special properties. This product has the characteristics of weather resistance and good hydrophobicity. Under the catalysis of some metal salt catalysts, it can be cross-linked on the surface of various substrates to form a waterproof film, which is moisture-proof, mildew-proof, rust-proof and breathable. Can be used as: fire extinguishing agent (dry powder), moisture-proof and hydrophobic treatment agent for glass, ceramics, leather, paper, metal, cement, marble and other building materials; cross-linking agent in addition type silicone rubber products; polyether modified silicone oil , basic synthetic raw materials for alkyl modified silicone oil, etc.
