PROBLEM TO BE SOLVED: To provide a catalyst composition for molding a polyurethane product having an action of delaying a start time of a polyurethane forming reaction and / or shortening a demolding time. The catalyst composition used to form the polyurethane product includes a gelling catalyst, a trimerization catalyst and a curing accelerator. The gelling catalyst is a tertiary amine, mono (tertiary amino) urea, bis (tertiary amino) urea or any combination thereof. The trimerization catalyst may be any known trimerization catalyst. The curing accelerator has at least one primary hydroxyl group and 5 to 17 main chain atoms selected from carbon, oxygen or both between a plurality of hydroxyl groups (provided that at least 5 of the main chain atoms are present) May be a diol having carbon). Alternatively or additionally, the curing accelerator is a polyol having at least two hydroxyl groups, at least two of which are primary hydroxyl groups, and having a molecular weight of 90-400 g / mol. Also good. [Selection figure] None |
