ABSTRACT:
A process for coating sheet metal is disclosed that comprises the steps of 1) cleaning the sheet metal to remove surface contaminants that may interfere with the coating adhering to the sheet metal; 2) pretreating the sheet metal to promote adhesion of the coating to the sheet metal; 3) applying an electron beam curable coating to the sheet metal that when curing is complete, adheres to the sheet metal; and, 4) exposing the coating on the sheet metal to an electron beam to cure the coating, the cleaning, pretreating and curing resulting in no emission of pollutants that need to be removed before the emission is released into the atmosphere.
