ABSTRACT:
A novel process for improving adhesion of polymeric bodies to paint coatings and substrates carrying paint coatings having the improved adhesion capability. Essentially the process involves the step of irradiating a paint coating comprising a synthetic polymer and where the coalesced residue of the paint coating has a critical surface tension of wetting of at least about 35 dynes per centimeter or less. In the preferred embodiment of the invention the paint coating is irradiated in the presence of a radiation sensitizer to increase the critical surface tension of wetting of the irradiated paint coat to about 40 dynes per centimeter or more.
