    Abstract: The invention provides a method for providing a low bake repair to a cured coating, especially a composite coating and low bake repair compositions for use therein. The method of the invention involves the provision of a cured coated surface and the application of a low bake repair coating to at least a portion of the cured coated surface. The low bake repair coating of the invention has (A) a film forming component comprising (a) a first component comprising a compound having appended thereto at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group, and (b) a second component comprising a compound reactive with said carbamate or urea groups on component (a), and (B) a catalyst comprising a compound selected from the group consisting of Al(ClO.sub.4).sub.2, Zr(ClO.sub.4).sub.2, and Al(NO.sub.3).sub.2. The low bake repair coating is cured at a temperature of less than 200.degree. F. for a time sufficient to cure the low bake repair coating.

    Abstract: The present invention relates to the preparation of water based coating compositions having extended storage stability. The composition includes separately stored polymeric binder component and a crosslinking component.These components are mixed prior to application over surfaces, such as, road surfaces. The polymeric binder component includes an anionically stabilized binder polymer having at least one reactive functional pendent moiety, or a blend of the binder polymer with a polyfunctional amine. The pot mix of the coating composition has extended storage stability. The waterborne road marking paints of the present invention exhibit improved wear resistance on road surfaces in terms of paint remaining on the road longer than waterborne road marking paints based on the storage stable component alone. The present invention provides road marking paints that can be applied by conventional road striping equipment and do not require special two component spray equipment.
