CA 2757973

The present invention is directed to curable cyanoacrylate-based formulation containing a multi-functional amine initiator. A dual function amine, particularly Quadrol, provides a highly desirable balance of maximum cure temperature and set-ting time of cure with the same higher viscosity, non-running cyanoacrylate formulation. The present invention is also directed to systems that utilize the inventive formulations and methods for use of such formulations.

La présente invention porte sur une formulation à base de cyanoacrylate durcissable contenant un initiateur d'amine multifonctionnel. Une amine à double fonction, en particulier le Quadrol, fournit un équilibre hautement souhaitable de température maximale de durcissement et de fixation du temps de durcissement avec la même formulation cyanoacrylate inactive à haute viscosité. La présente invention porte également sur des systèmes utilisant les formulations de l'invention et sur des procédés d'utilisation de telles formulations.
