Abstract[English]
The present disclosure is directed to an one-component (1K) curable composition comprising, based on the weight of the composition: from 50 to 90 wt.% of a) at least one epoxy resin which has been modified with a hydrophobic elastomer, said modified epoxy resin having an epoxide equivalent weight of from 200 to 1000 g/eq; up to 15 wt.% of b) at least one epoxy resin distinct from the modified resin of part a); c) at least one compound which provides at least two amine hydrogens reactive toward epoxide groups; and, from 0.01 to 5 wt.% of d) at least one accelerator, wherein the composition is characterized by a molar ratio of epoxide groups to epoxide-reactive groups of from 0.5:1 to 1.4:1.[French]
La présente divulgation concerne une composition durcissable à un composant (1K) comprenant, sur la base du poids de la composition : de 50 à 90 % en poids de a) au moins une résine époxy qui a été modifiée avec un élastomère hydrophobe, ladite résine époxy modifiée ayant un poids équivalent d'époxyde allant de 200 à 1 000 g/éq ; jusqu'à 15 % en poids de b) au moins une résine époxy distincte de la résine modifiée a) ; c) au moins un composé qui fournit au moins deux hydrogènes d'amine réactifs vis-à-vis des groupes époxyde ; et, de 0,01 à 5 % en poids de d) au moins un accélérateur, la composition étant caractérisée par un rapport molaire des groupes époxyde aux groupes réactifs à l'époxyde allant de 0,5:1 à 1,4:1.
