Organotin sulfonate catalysts and their manufacture

摘要

Dual cure organotin salts of strong organic acids, the use of such salts as catalysts and an improved process for producing the catalysts are provided. The catalysts are capable of effectively catalyzing esterification and transesterification reactions and urethane, silicone, melamine, ester and acrylic forming reactions and can simultaneously catalyze more than one reaction in a mixture of urethane, silicone, amino, ester and acrylic polymer forming reactants to produce a polymer mixture.
