Patent

CA 2280984

L'invention se rapporte aux formulations polyuréthane à base de polybutadiène hydroxylé catalysées par un dérivé de l'imidazole N-substitué. Ce type de catalyse remplace avantageusement les catalyseurs classiques à base de sel de mercure. En effet, il ne pose pas de problème écologique et permet une montée de viscosité particulière autorisant un temps de travail allongé et une prise rapide.
