Organic tin additive

Dibutyltin dilaurate is an organic tin additives, and can be soluble in benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether and other organic solvents and all industrial plasticizers, but insoluble in water. Multipurpose high-boiling organic tin catalyst circulation of dibutyltin dilaurate are usually specially treated liquefaction, and at room temperature as a pale yellow or colorless oily liquid, when low temperature as white crystals, and it can be used for PVC additives, it also has excellent lubricity, transparency, weather resistance, and better resistance for sulfide pollution. It can also uesd the stabilizer of the soft transparent products and efficient lubricants in hard transparent products, and can also be used acrylate rubber and rubber carboxyl crosslinking reaction, the catalyst of synthesis of polyurethane foam and polyester synthetic, and RTV silicone rubber.

Air & Water Reactions

Dibutyltin dilaurate may be sensitive to air or heat. . Insoluble in water.

Reactivity Profile

Dibutyltin dilaurate is strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents.

Fire Hazard

Dibutyltin dilaurate is combustible.

Safety Profile

Poison by ingestion and intraperitoneal routes. A skin and eye irritant. Avoid the vapor produced by heating. Combustible when exposed to heat or flame; reacts with oxidizers. When heated to decomposition it emits acrid smoke and fumes. See also TIN COMPOUNDS
