ABSTRACT:
This invention is directed to flexible basecoat/clearcoat coating systems which have excellent adherence to metal and plastic substrates and possess superior weathering properties. The clearcoat composition comprises hydroxy-containing urethane modified polyester, made by reacting a urethane modified diol with polyol and diacid component, crosslinkable with polyisocyanates. The basecoat composition comprises hydroxy-containing urethane modified polyesters, made by reacting hydroxy functional polyester with diisocyanate, crosslinkable with amine-aldehyde resins, and pigment. Optionally, either or both compositions may comprise a high molecular weight linear polyurethane.
