ABSTRACT:
An acid cured coating composition containing a hydroxyfunctional acrylic or polyester resin and a 1,3,5-triazine-2,4,6-tris-carbamate. Also provided is an acid cured coating composition containing a hydroxyfunctional acrylic or polyester resin, a crosslinking agent such as a melamine-formaldehyde or a related aminoresin, and a co-crosslinking agent derived from a triazine tris-carbamate such as 2,4,6-tris-(butoxycarbonylamino)-1,3,5-triazine. Also provided is an improved method of coating using the above coating compositions. The coating compositions described in this invention have lower cure temperatures, lower formaldehyde emissions during cure, and produce films and objects which have superior environmental etch resistance than the conventional melamine-formaldehyde coatings which do not have a triazine tris-carbamate co-crosslinker.
