In which products is dibutyltin dilaurate used

Dibutyltin dilaurate, abbreviated as DBTDL

Product Introduction:

DBTDL, short for dibutyltin dilaurate catalyst, is a high boiling point multi-purpose organic tin catalyst that has undergone special liquefaction treatment. It is a light yellow or colorless oily liquid that forms white crystals at low temperatures. Soluble in most common solvents such as benzene, toluene, ethanol, acetone, ethyl acetate, chloroform, carbon tetrachloride, benzene, ethanol, petroleum ether, and various industrial plasticizers, insoluble in water, it is an important component of catalytic systems in various chemical reactions. It is not only used as an efficient catalyst in the manufacture of wood coatings, PU coatings, metal inks, adhesives and sealants, but also can be used as a catalyst for silicone rubber, a catalyst for the crosslinking reaction of acrylate rubber and carboxyl rubber, a catalyst for the synthesis of polyurethane foam plastics, and an efficient lubricity and stability in PVC plastic products. A good catalytic effect can be achieved with a dosage of 0.01-2%, and the available temperature range is 80-240 ℃. The available temperature range is 80-240 ℃.

Main uses:

★ Drying agents in the paint and ink industry have excellent drying properties for coatings such as bimolecular polyurethane, polyester, nitro paint, curing agents for coatings, inks, and moisture curing coatings. They can accelerate the curing of PU in polyurethane high-end furniture paint, promote rapid drying of the paint film, and obtain a smooth, flat, and extremely hard paint film; In PU coatings, its oxidation stability is good.

Stabilizers and lubricants for PVC products. PVC soft transparent or semi soft products have good lubricity, transparency, weather resistance, and compatibility with plasticizers when used in combination with metal soaps or epoxy compounds such as barium stearate and cadmium stearate. They do not spray frost, have no sulfur pollution, and have no adverse effects on heat sealing and printability. Such as soft film, flexible film, plastic shoes, flexible hoses, and PVC conveyor belts. Especially as a catalyst for polyurethane foam products. In PVC hard products, this product can be used in combination with maleic acid organotin or thiol organotin to improve the flowability of resin materials.

★ It is used as catalyst and foaming activator in polyurethane foam, PVC foam and silicone rubber synthetic materials.

Used as a synthetic catalyst in various adhesives.
