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.
L'invention porte sur des sels d'étain organiques d'acides organiques forts, à double durcissement, sur l'emploi de ces sels comme catalyseurs et sur une méthode améliorée pour la production desdits catalyseurs. Ces derniers permettent de catalyser efficacement les réactions d'estérification et de transestérification, ainsi que les réactions de formation d'uréthane, de silicone, de mélamine, d'ester et de composé acrylique; de plus ils peuvent catalyser simultanément plus d'une réaction dans un mélange de réactifs générateur d'uréthane, de silicone, d'amine, d'ester et de polymère acrylique, pour la production d'un mélange polymérique.
