Abstract:
A method for providing a composite coating having an improved appearance, comprising:applying a first coating to a substrate;applying a second coating to the first coating to provide a composite coating, the second coating comprising,(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 wrinkle reducing catalyst comprising a compound of the formula:M.sub.y (L).sub.xwherein M is a metal having an empty or full d orbital wherein the pk.sub.a of the aqua ion of M is less than or equal to 12, L is a ligand wherein the pk.sub.a of the parent acid is .gtoreq.-10 and is .ltoreq.4, x is an integer which is a multiple of the charge of M, y is an interger which is a multiple of the charge of L, x and y selected so that ML is charge balanced, andsubjecting the composite coating to a temperature between about 200.degree. F./93.degree. C. to 395.degree. F./200.degree. C. for a time sufficient to provide a cured composite coating.
