Abstract: The present disclosure is directed to a coating composition for producing coatings sag-free at high coating thicknesses, being quick dry and having good appearance. This disclosure is further directed to a coating composition comprising a crosslinking activator comprising: a) one or more alkylated melamines that are essentially unreactive to a polyisocyanate, and b) a polyurea sag control agent formed by reacting an amine and an isocyanate in the presence of the alkylated melamines. The coating composition can be used to form coating layers having a sag-free wet coating thickness in a range of from 10 to 36 mil (about 0.25 to 0.91 mm). The coating composition can be particularly suitable for vehicle coatings.

Abstract: The present disclosure is directed to process for forming a coating layer curable at ambient temperature. This disclosure is further directed to a process for forming a coating layer using a coating composition comprising a crosslinkable component and a crosslinking component that comprises: (a) one or more alkylated melamines that are essentially unreactive to a polyisocyanate, and (b) a polyisocyanate. The process and the coating composition can be particularly suitable for vehicle coatings.

Abstract: The present disclosure is directed to a waterborne coating composition having neutral pH that is low foaming and forms dry coating layer that has high hardness and high gloss. This disclosure is further directed to a coating composition comprising a crosslinking component comprising: (a) one or more alkylated melamines that are essentially unreactive to a polyisocyanate; and (b) a polyisocyanate. The coating composition can be particularly suitable for vehicle coatings and other industrial or consumer applications.

Abstract: A process for providing a coating with improved adhesion to a substrate is provided. The coating composition comprises an epoxy function polymer, a fully alkylated melamine resin and an amidoamine. The process involves forming a mixture of the film forming components and allowing the mixture to mature before adding an acid catalyst. The result is a layer of the coating composition with a high degree of adhesion to the substrate.
