Patent

CA 2575613

The invention is directed to methods of preparing compositions used to manufacture polyurethane foams. The invention provides methods for making compositions used to make polyurethane foams that include amine catalysts, but formulated such that catalytic potency is not diminished over time before the forming of a foam.

La présente invention a trait à des procédés de préparation de compositions destinées à la fabrication de mousses polyuréthanne. L'invention a trait à des procédés pour la fabrication de compositions destinées à la fabrication de mousses polyuréthanne comprenant des catalyseurs à base d'amine, mais formulés de sorte que la puissance catalytique ne diminue pas dans le temps avant la formation d'une mousse.
