Title (EN) FILM FORMING BINDER FOR COATING COMPOSITIONS AND COATING COMPOSITIONS COMPRISING SAME
(FR) LIANT FILMOGENE DESTINE A DES COMPOSITIONS DE REVETEMENT ET COMPOSITIONS DE REVETEMENT COMPRENANT CELUI-CI
Abstract: front page image
(EN)The current invention provides a film forming binder comprising: (1) 45 to 99 wt.% of a polyester polyol comprising cycloaliphatic moieties, and (2) 55 to 1 wt.% of a polyurethane polyol comprising cyclic moieties, with the proviso that the Tg of the polyurethane polyol is higher than the Tg of the polyester polyol. Also disclosed are coating compositions comprising such film forming binders and a crosslinker, a process for the curing of such coating compositions, and the use of such coating compositions on substrates.
(FR)La présente invention concerne un liant filmogène comprenant: (1) de 45 à 99 % en poids d'un polyol de polyester comprenant des fractions cycloaliphatiques, et (2) de 55 à 1 % en poids d'un polyol de polyuréthanne comprenant des fractions cycliques, à condition que la TG du polyol de polyuréthanne soit supérieure à celle du polyol de polyester. Des compositions de revêtement comprenant de tels liants filmogènes et un agent réticulant, un procédé de durcissement de telles compositions de revêtement, ainsi que l'utilisation de telles compositions de revêtement sur des substrats sont également décrites.
