Abstract
Abstract This invention relates to a strippable wax coating containing an ethylene-vinyl acetate polymeric composition and a stripping agent which is either an N-substituted fatty acid amide or a nitrogen containing compound containing a fatty acid residue. Particularly preferred are wax compositions which contain as the stripping agent an N-substituted fatty acid amide containing a fatty acid residue having from 10 to 17 carbon atoms. The compositions can also contain minor amounts of a mineral oil to increase the strippability.
