What is Butylchlorodihydroxytin?
Description
Butylchlorodihydroxytin also known as Butyltin chloride dihydroxide, butyl(chloro)stannanediol, is one of several organotin compounds which are active as an esterification catalysts at a temperature range of 200-230 °C. It is a non-acidic white solid which has C4H11ClO2Sn as chemical formula. It dissolves by reaction on heating with alcohols or carboxylic acids. The resulting active is soluble in ester systems and remains in the ester product.
The Uses of Butylchlorodihydroxytin
Butylchlorodihydroxytin is an amorphous, hydrolytically stable butyl tin chloride dihydroxide. It can be used for esterification, polycondensation and transesterification reactions. The catalyst is used to synthesize saturated polyester resin for powder coatings. Other uses include:
production of unsaturated polyester resins for gel coat, sheet molding, and cast molding applications
in transesterification reactions run at temperatures between 140-180°C to produce esters and anti-oxidants
in the production of PBT engineering resins for the automotive and construction markets
