dibutyl tin dilaurate


Dibutyltin dilaurate is an organic tin additive. It is soluble in organic solvents such as benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether, and all industrial plasticizers. It is insoluble in water. The high-boiling, multi-purpose organotin catalysts on the market are usually dibutyltin dilaurate which has been specially liquefied. It is a light yellow or colorless oily liquid at room temperature and turns into a white crystal at low temperature. It can be used as a plastic additive for polyvinyl chloride. It has excellent lubricity, transparency and weather resistance. Good resistance to sulfide pollution. It is used as a stabilizer in soft transparent products and as a high-efficiency lubricant in hard transparent products. It can also be used as a catalyst for the crosslinking reaction of acrylate rubber and carboxyl rubber, synthesis of polyurethane foam and polyester, and room temperature vulcanized silicone rubber. catalyst

Light yellow or colorless liquid, white crystal at low temperature

1) Stabilizer and lubricant for PVC products. Soft transparent products or semi-soft products, combined with barium stearate, cadmium stearate and other metal soaps or epoxy compounds have good lubricity, transparency, weather resistance, compatibility with plasticizers, not Frost spray, no sulfide pollution, no adverse effect on heat sealability and printability. Such as: soft film, film, plastic shoes, hoses and PVC conveyor belts. It can be used together with organotin maleate or thiol organotin in hard products to improve the fluidity of resin materials.

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

3) Used as a synthesis catalyst in various adhesives.
