Disclosed are high solids, one-component, storage stable coating compositions that include an epoxy resin comprising more than one 1,2-epoxy groups per molecule; a hydrocarbon compound having a softening point of from 50°C to 140°C; an alkoxy-functional and/or silanol-functional silicone; and a ketimine curing agent comprising a reaction product of reactants comprising a polyalkyldiamine component and a ketone component. Also disclosed are substrates at least partially coated with a coating deposited from such composition and methods for coating substrates with such compositions.
Cette invention concerne des compositions de revêtement stables à la conservation, à composant unique et à teneur en solides élevée, lesdites compositions comprenant une résine époxy contenant plusieurs groupes 1,2-époxy par molécule ; un composé hydrocarboné ayant un point de ramollissement compris entre 50 °C et 140 °C ; une silicone alcoxy-fonctionnelle et/ou silanol-fonctionnelle ; et un agent de vulcanisation à base de cétimine comprenant un produit réactionnel de réactifs contenant un composant polyalkyldiamine et un composant cétone. L'invention concerne par ailleurs des substrats au moins partiellement recouverts d'un revêtement constitué de cette composition et des méthodes de recouvrement de ces substrats avec ces compositions.
