Beschreibung
Zusammenfassung:	A high solids polymer resin coating composition cross-linked with alkylated melamine resins possessing improved intercoat adhesion in multiple coating applications. A mixed methylated isobutylated melamine resin as a cross-linking agent for the high solids polymer resin coating composition surprisingly substantially eliminates intercoat adhesion failure without any negative effects on overall coating properties and performance. The backbone polymer of the composition may advantageously be acrylic resin, a polyester resin or mixtures thereof while the mixed methylated isobutylated melamine resin cross-linking agent is advantageously predominantly monomeric poly(methoxy isobutoxymethyl) melamine resin with an average methoxy content of 1-5 and an average isobutoxy content of 5-1, per triazine.
