| description | A coating composition includes (a) a melamine resin having imino and methylol functional groups that together include 30 mole % or greater of the total functionality of the melamine resin; and (b) at least one polymer reactive with (a) that is obtained from components including polytetrahydrofuran and a carboxylic acid or anhydride thereof. The polytetrahydrofuran includes greater than 20 weight % of the components that form the polymer (b) and the carboxylic acid or anhydride thereof includes greater than 13 weight % of the components that form the polymer (b). The polymer (b) has an acid value ranging from 40 to 60 based on the total resin solids of the polymer (b).
La présente invention concerne une composition de revêtement comprenant (a) une résine mélamine ayant des groupes fonctionnels imino et méthylol qui contiennent ensemble 30 % en mole ou plus de la fonctionnalité totale de la résine mélamine ; et (b) au moins un polymère réactif avec (a) qui est obtenu à partir des constituants comprenant le polytétrahydrofurane et son acide carboxylique ou anhydride. Le polytétrahydrofurane comprend plus de 20 % en poids des constituants qui forment le polymère (b) et son acide carboxylique ou anhydride comprend plus de 13 % en poids des constituants qui forment le polymère (b). Le polymère (b) présente un indice d?acidité compris entre 40 et 60 sur la base des matières solides totales de résine du polymère (b). |
