Abstract

L'invention porte sur un adhésif à deux composants comportant (A) une première partie d'un prépolymère de polyuréthane présentant un fragment réactif d'isocyanate, et (B) une deuxième partie d'un durcisseur formée de i) une polyurée comprenant le produit de réaction d'une polyamine et d'un polyisocyanate, dispersé dans un prépolymère de polyuréthanne à base polyétherpolyol présentant un fragment réactif hydroxyle et facultativement un plastifiant, ii) un composé présentant au moins un fragment d'oxazolidine susceptible de réagir avec un isocyanate dans des conditions de durcissement, et (iii) un catalyseur capable de catalyser la réaction des fragments isocyanate et hydroxyles en présence d'humidité. L'adhésif objet de cette invention donne un temps raisonnable de sortie de chaîne pour les verres qui viennent d'être posés dans une automobile. Ce temps est de préférence de 60 minutes ou mieux de 30 minutes après l'application de l'adhésif. Ledit adhésif offre également un temps d'ouvrabilité raisonnable de 10 à 12 minutes. De plus la contrainte de cisaillement de recouvrement après écoulement du temps de sortie de chaîne est de préférence de 1033 kPa, ou mieux encore, de 1723 kPa selon la norme ASTM D-3163.
