CA 2554648

An improved economically produced clean room ceiling tile formed as a composite comprising a base board and a finish coated paper facer laminated to the base board. The base board is preferably made with excess thickness and is machined to a desired caliper. The machined board is sealed with a clay coating and thereafter coated with a water-based adhesive. The paper facer is laminated to the board with the water-based adhesive and is finish coated with a water-based wet scrubbable coating. The paper facer is easy to laminate, exhibits excellent coverage of surface defects in the base board surface, is fully compatible with the water-based finish coating, and contributes to the sag resistance of the tile.
