Abstract
This invention involves a unique wood and furniture coating composition comprising about 50 to about 85% by weight of an acrylated cellulosic, about 15 to about 45% by weight of an acrylated oligomer about 0.1 to about 10% by weight of a ultraviolet photoinitiator and sufficient solvent to render the resulting solution handleable under processing conditions. The resulting coating may be applied by a unique process that involves spraying the coating over a base coated wood substrate, flashing the solvent off, rubbing, sanding or otherwise processing the coating and then ultraviolet curing the coating by subjecting the coating to ultraviolet curing conditions. The resulting coating possesses excellent cured state film properties and good chemical resistance. Its film properties are at least equivalent to prior art cellulose nitrate coatings but it is far superior to these coatings in terms of its chemical and water resistance. In comparison to prior art urea/formaldehyde curable systems, the instant invention provides far superior processing and film appearance properties.
