Abstract
This invention pertains to a method and apparatus for producing a cured resinous coating which exhibits a reduced gloss level. In a preferred embodiment, the cured resinous coating which exhibits a reduced gloss level is a wear resistant coating and is superimposed on a resilient floor covering material.
Claims10
A method for producing a radiant energy cured resinous coating having a reduced gloss level, wherein said coating does not require the presence of flatting pigments to achieve gloss reduction, which method comprises:
- (a) coating the surface of a substrate with a liquid resinous coating composition curable by radiant energy;
- (b) treating at least a portion of the surface of the liquid resinous coating with a corona discharge sufficient to reduce the gloss level of the coating in the treated portion;
- and
- (c) exposing the liquid resinous coating having a reduced gloss level to a dosage of radiant energy sufficient to polymerize the coating and set the reduced gloss level.
A method for producing a combined radiant energy and moisture cured resinous coating having a reduced gloss level, wherein said coating does not require the presence of flatting pigments to achieve gloss reduction, which method comprises:
- (a) coating the surface of a substrate with a liquid resinous coating composition curable by a combined radiant energy and moisture cure;
- (b) treating at least a portion of the surface of the liquid resinous coating with a corona discharge sufficient to reduce the gloss level of the coating in the treated portion;
- (c) exposing the liquid resinous coating having a reduced gloss level to a dosage of radiant energy sufficient to polymerize the radiant energy curable components of the coating and set the reduced gloss level;
- and,
- (d) subjecting the radiant energy cured coating to a moisture cure to fully cure the coating.
