ABSTRACT:
Powder coatings are described which are curable by means of exposure to radiation, typically ultraviolet radiation, and the electrostatic deposition thereof onto substrates of wood or similar materials. Free radical curing coatings are described using specific chemical formulations of acrylourethane resins, unsaturated polyester resins and mixtures thereof in combination with morpholino, phenol, phosphine and ketal photoinitiators. Electrostatic application onto wooden substrates involves grounding of the substrate, electrostatic deposition and, typically, heating the substrate to flow the coating into a smooth finish prior to radiation curing. Moisture and humidity controls may also be used to improve the electrostatic coating process.
