Description and features
Viacat 4101 (Butyltin chloride dihydroxide) is one of several organ tin 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.
Viacat 4101 is recommended for preparation of esters such as trioctyltrimellitate and unsaturated and saturated polyester. In addition Viacat 4101 is used in the production of powder coating resins.
Butyltin chloride dihydroxide is also known as butylchlorodihydroxytin and butyl(chloro)stannanediol.
