Blowing reaction catalyst composition that provides cell opening of the resulting polyurethane foam |
| abstract |
A method for preparing a polyurethane foam which comprises reacting inorganic polyisocyanate and a polyol in the presence of a catalyst composition comprising a blowing catalyst and a gelling catalyst, the improvement which comprises employing a blowing catalyst consisting essentially ofn (a) 25 to 80 wt% pentamethyldiethylenetriamine and (b) 20 to 75 wt% bis(dimethylaminopropyl)methylamine. The catalyst composition provides the resulting polyurethane foam with improved breathability. |
