Dibutyltin dilaurate/CAS 77-58-7


Dibutyltin dilaurate is an organotin additive, soluble in organic solvents such as benzene, toluene, carbon tetrachloride, ethyl acetate, chloroform, acetone, petroleum ether and all industrial plasticizers, insoluble in water. Commercially available high-boiling multi-purpose organotin catalyst dibutyltin dilaurate is usually after special liquefaction, light yellow or colorless oily liquid at room temperature, white crystals at low temperatures, can be used for PVC plastic additives, with excellent lubricity, transparency, weather resistance. It has excellent lubricity, transparency and weather resistance. It has good resistance to sulfide pollution. In soft transparent products as stabilizer, in hard transparent products as efficient lubricant, can also be used as acrylate rubber and carboxy rubber crosslinking reaction, polyurethane foam synthesis and polyester synthesis catalyst, room temperature vulcanization of silicone rubber catalyst.
