CA 2758431

The present invention provides a composi-tion comprising a solvated aromatic amine and a liquid car-rier, wherein said solvated aromatic amine is the reaction product of an aromatic amine and at least one of any anhy-dride, an isocyanate or an acid in the liquid carrier. The present invention also provides a method of preparing a composition comprising a solvated aromatic amine and a liquid carrier, said method comprising the steps of provid-ing a reaction mixture comprising: a) an aromatic amine; b) at least one of an anhydride, an isocyanate or an acid; and c) a liquid carrier; and heating the reaction mixture at an el-evated temperature to provide the solvated aromatic amine in the liquid carriers. The present invention further pro-vides the use of the compositions for the preparation of the curable compounds and for gasoline resistant coatings.

La présente invention porte sur une composition comprenant une amine aromatique solvatée et un véhicule liquide, ladite amine aromatique solvatée étant le produit de la réaction d'une amine aromatique et d'au moins un composé parmi un anhydride, un isocyanate ou un acide dans le véhicule liquide. La présente invention porte également sur un procédé de préparation d'une composition comprenant une amine aromatique solvatée et un véhicule liquide, ledit procédé comprenant les étapes consistant à se procurer un mélange réactionnel comprenant : a) une amine aromatique ; b) au moins un composé parmi un anhydride, un isocyanate ou un acide ; et c) un véhicule liquide ; et chauffer le mélange réactionnel à une température élevée pour fournir l'amine aromatique solvatée dans les véhicules liquides. La présente invention porte en outre sur l'utilisation des compositions pour la préparation des composés durcissables et pour des revêtements résistants à l'essence.
