Patent

CA 2556700

The present invention pertains to the co-catalysis of autocatalytic amine- based polyols with acid blocked, gelling, amine catalysts, and to the use of this catalyst combination in the production of low density polyurethane foams having improved aging characteristics and reduced VOC~s (Volatile Organic Compounds) emissions.

La présente invention concerne la co-catalyse de polyols autocatalytiques à base d'amine avec des catalyseurs en amine, gélifiants et bloqués par un acide et l'utilisation de cette association de catalyseurs dans la production de mousses de polyuréthane de faible densité ayant de meilleures caractéristiques de vieillissement et des émissions de COV (composés organiques volatils) réduites.
