Abstract

L'invention concerne un agent de revêtement aqueux à deux composants à base d'un ou plusieurs polyols et d'un ou plusieurs polyisocyanates, en particulier pour le revêtement de substrats en matière plastique, dans lequel le ou les polyols se présentent dans un premier composant et le ou les polyisocyanates se présentent dans un deuxième composant, et les composants sont mis en présence l'un de l'autre avant application. L'agent de revêtement renferme, une fois que les composants sont réunis, les constituants ci-après: 10 à 40 % en poids d'un ou plusieurs polyols dont la moyenne arithmétique des masses molaires est comprise entre 300 et 2 000 000, un indice d'OH de 10 à 400 mg KHO/g et une teneur atteignant 400 milliéquivalents/100 g de résine solide en groupes ioniques et/ou en groupes transformables en groupes ioniques, 0,5 à 10 % en poids d'une ou plusieurs oléfines chlorées et/ou non chlorées, 1 à 35 % en poids de pigments électroducteurs et/ou de charges, 5 à 30 % en poids d'un ou plusieurs solvants organiques, 25 à 75 % en poids d'eau et 1 à 30 % en poids de polyisocyanates ayant en moyenne au moins deux groupes isocyanates libres par molécule, la somme des constituants précités s'élevant à 100 % en poids et la proportion de composants polyisocyanates et de composants polyols étant choisie de façon que le rapport entre le nombre de groupes NCO réactifs et le nombre de groupes OH soit compris entre 5:1 et 0,5:1.
