Dibutyltin dilaurate CAS#77-58-7
Excellent solubility — Easily dissolves in a wide range of organic solvents and industrial plasticizers.
Versatile applications — Used as an additive, stabilizer, lubricant, and catalyst across PVC, rubber, polyurethane foam, polyester, and silicone rubber industries.
Enhances product properties — Improves lubricity, transparency, weather resistance, and resistance to sulfide contamination.
High thermal stability — Functions effectively as a high-boiling organic tin catalyst, stable under various temperature conditions.
Dibutyltin dilaurate is an organic tin additive that is soluble in organic solvents such as benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether, and most industrial plasticizers, but insoluble in water. This versatile, high-boiling organic tin catalyst is typically treated for liquefaction and appears as a pale yellow or colorless oily liquid at room temperature, turning into white crystals at low temperatures. It is commonly used as an additive in PVC, providing excellent lubricity, transparency, weather resistance, and resistance to sulfide contamination. Dibutyltin dilaurate also serves as a stabilizer for soft transparent products and an efficient lubricant for hard transparent products. Additionally, it acts as a catalyst in the crosslinking of acrylate rubber and carboxyl rubber, in the synthesis of polyurethane foam, polyester, and RTV silicone rubber.

Di-n-butyltin dilaurate is utilized as a catalyst in the production of polyurethanes and transesterification reactions. It plays a key role in the vulcanization of silicones and serves as a stabilizer in polyvinyl chloride (PVC). Additionally, it functions as a rust inhibitor for polyurethanes, polyols, and silicones, and is also used as a fuel additive.
