Use of tin salts of a carboxylic acid in the production of polyurethane systems

摘要

Catalyst system comprises a metal salt of carboxylic acid (in which a hydrogen or hydrocarbon is bound to the carbonyl-carbon atom and provided that the carboxylic acid does not exclusively comprise a single ethyl- or n-propyl branching at second position). Independent claims are included for: (1) use of the catalyst system for the preparation of polyurethane coating, polyurethane adhesive, polyurethane sealant, polyurethane elastomer or polyurethane foam materials; and (2) a polyurethane system comprising a carboxylic acid or its salt in which the carbonyl carbon is bound to a hydrocarbon, provided that the carboxylic acid does not contain single ethyl- or n-propyl branching at second position.
