CAS 77-58-7


Dibutyltin dilaurate is an organic tin additive, soluble in benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether Such as organic solvents and all industrial plasticizers, insoluble in water. The high-boiling multi-purpose organotin catalyst dibutyltin dilaurate circulating on the market is usually after a special liquefaction treatment. It is a light yellow or colorless oily liquid at room temperature and becomes a white crystal at low temperature. It can be used as a PVC plastic additive. It has excellent lubricity, transparency and weather resistance. Good resistance to sulfide pollution. Used as a stabilizer in soft and transparent products, as a high-efficiency lubricant in hard and transparent products, it can also be used as a catalyst for the cross-linking reaction of acrylate rubber and carboxyl rubber, polyurethane foam synthesis and polyester synthesis, and room temperature vulcanized silicone rubber Catalyst

Light yellow or colorless liquid, low temperature into white crystals

1) Stabilizer and lubricant for PVC products. Soft transparent products or semi-soft products, used with metal soaps or epoxy compounds such as barium stearate and cadmium stearate, have good lubricity, transparency, weather resistance, and compatibility with plasticizers. Frost, no vulcanization pollution, no adverse effects on heat sealability and printability. Such as: soft film, film, plastic shoes, hose and PVC conveyor belt, etc. It can be used in combination with organotin maleate or organotin mercaptan in hard products to improve the fluidity of resin materials.

2) Used as a catalyst and foaming activator in polyurethane foam and silicone rubber synthetic materials.

3) Used as a synthesis catalyst in various adhesives.
