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.
