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

Advantage:
1 . It has excellent lubricity, high transparency.
2 . And cadmium, barium metal soaps and with a synergistic effect.
3. Weather resistance.

Usage:
1.Thermal stabilizers for PVC, silicone rubber curing agent, polyurethane foam catalyst
2.Used as a stabilizer in plastics, rubber curing agent
3.It can be used as PVC heat stabilizers, organotin stabilizers used in the earliest varieties, less heat will tributyltin maleate, but excellent lubricity, weather resistance and transparency can, and plasticizers good compatibility, non-blooming, non-sulfide pollution, no adverse effects on heat sealing and printability. Because of its liquid at room temperature, so the plastic dispersion of solid stabilizer relatively good. The product is mainly used in soft transparent products or semi-soft products, generally in an amount of 1-2%. And cadmium stearate, barium stearate or other metal soaps and epoxy compounds with a synergistic effect. In hard products, the product can be used as a lubricant, and maleic acid organic tin or thiol-containing organic tin and used to improve the fluidity of the resin material. Compared with other organic tin, the goods early color large will cause yellow discoloration. The product can also be used as catalysts, silicone rubber curing agents for polyurethane synthesis. In order to enhance the product thermal stability, transparency, compatibility with resins, as well as improve the impact strength for hard products when its other properties, has now developed a number of modified varieties. Lauric acid is generally added to the category of pure fatty acids, some also joined the epoxy ester or other metal soap stabilizer.
4. heat stabilizers for soft transparent PVC products production, can prevent sulfide pollution.
5. to promote rapid curing one-component moisture-curing PU paint, two-component PU coatings. Significantly shorter polyurethane finish at the end can be polished.
6.Promote one-component and two-component silicone rubber mold plastic fast gelling.
7.For the silane crosslinked polyethylene crosslinked condensation.
8.Lauric acid type organic tin stabilizer. Mainly used in soft PVC products through processing, such as: films, hoses, leather, polyvinyl chloride fiber. Polyurethane foam can also be used in the synthesis of the catalyst, and catalyst in the silicone rubber. And vinyl chloride copolymer fiber thermal stabilizers polyamide and phenolic resin light and heat stabilizers, polyurethanes and silicone paint driers.

Brief manufacture process:
Dibutyl tin oxide and lauric acid condensation at 60 ℃. After condensation, vacuum dehydration, cooling, pressure filtration derived products.
