Patent

CA 2440471

The present invention relates to adducts obtainable by reaction of: A) an amine compound containing 2 or more than 2 amino groups; with B) a polylakylene glycol monoglycidyl ether of general formula (I), in which R independently of one another (for n > 1), is an -H or -CH3 radical, and n = 1 to 50, characterized in that the reaction ratio of components A) and B) is selected in such a way that the resultant adduct contains 2 or more than 2 amine hydrogen groups; to curable compositions based on these adducts with epoxy resins, and to the use of these curable compositions as casting resin, adhesive, matrix resin, tooling resin or as coating composition, in particular for self-flowing coatings.

L'invention concerne des adduits obtenus par réaction de: A) un composé amine contenant 2 ou plus de 2 groupes amino, et de B) un monoglycidyléther de polyalkylène glycol de formule générale (I), dans laquelle R représente, de façon indépendante (pour n > 1), un -H ou un groupe -CH¿3? , et n = 1 à 50, caractérisés en ce que le rapport réactionnel des composants A) et B) est choisi de telle façon que l'adduit résultant contienne 2 ou plus de 2 groupes amine contenant de l'hydrogène. L'invention concerne aussi des compositions durcissables basées sur ces adduits avec des résines époxy, ainsi que les utilisations de ces compositions durcissables en tant que résine de moulage, colle, résine matricielle, résine d'outillage ou en tant que composition de revêtement, notamment pour des revêtements s'écoulant naturellement.
