HIGH SOLID COATING COMPOSITIONS

摘要

The invention is directed to solvent-based coating compositions comprising a binder component and a crosslinking component, wherein the binder component comprises at least one hydroxy-functional polyether A) having at least two secondary hydroxyl groups per molecule, a number average molecular weight Mn in the range of 200 to 5,000 and a polydispersity of < 2, wherein the polyether A) is obtained from at least one polyol Aa) having at least three hydroxyl groups and at least one monoglycidyl ester Ab) of a branched monocarboxylic acid, having 5 carbon atoms in the molecule, and wherein the crosslinking component comprises at least one cross-linking agent B), which is capable of entering into a cross-linking reaction with the hydroxyl groups of the hydroxy-functional polyether A). The coating compositions have a low content of volatile organic compounds and are suitable as clear coat or pigmented top coat for automotive and industrial coating.
