ABSTRACT:
A method for producing an abrasion-resistant, ultraviolet radiation cured coating on a surface of a polymeric substrate is disclosed, as well as the article produced from the method. The uncured coating material which is substantially free of non-reactive volatile components is (i) applied to the substrate (ii) heated along with the substrate to a temperature sufficient to drive a portion of the coating material into a region beneath the surface of the substrate, (iii) and cured onto the substrate by exposing the coating material under anaerobic conditions to sufficient ultraviolet radiation to cure the coating material. Heating of the solvent-free coating prior to ultraviolet radiation cure and while in contact with the substrate results in improved adhesion of the coating to the substrate.
