Abstract

La présente invention concerne de manière générale un adhésif à deuxcomposants et un procédé d'injection de celui-ci. L'adhésif à deux composants comprend un premier composant et un second composant. Le premier composant comprend une ou plusieurs résines époxy et/ou résines fonctionnalisées par époxy. Le second composant comprend un ou plusieurs composés acides, contenant du phosphore, comprenant un acide minéral et/ou un ou plusieurs esters phosphates acides. De préférence, les premier et second composants ont chacun une viscosité d'environ 30 000 cP ou moins à 25°C et un taux de cisaillement de 10 1/sec de telle sorte qu'après mélange des premier et second composants formant un adhésif mixte, l'adhésif mixte peut être injecté suivant une ligne de liaison définie par une dimension entre deux surfaces à coller par l'adhésif mixte.
