COMPOSIZIONE PER CATALIZZATORE PER LA PREPRAZIONE DI POLIMERI CELLULARI RIGIDI DI ISOCIANURATI MODIFICATI CON URETANO

摘要

The friability exhibited by urethane-modified isocyanurate foams prepared using alkali metal salts of carboxylic acids as the catalyst is reduced by employing certain organotin compounds or stannous salts of carboxylic acids as a co-catalyst.
