Document Type and Number:
Japanese Patent JPH06155415
Kind Code:
A
Abstract:
PURPOSE: To repeatedly use a non-plywood wooden board as a concrete panel material excellent in water resistance and chemical resistance by bonding a coating material such as a polyolefin film to the surface of the board through a hot melt adhesive.
CONSTITUTION: A hot-melt adhesive is applied to the upper and rear surfaces of an MDF board to be cooled to room temp. and a polyolefin film is subsequently applied and bonded to the upper and rear surfaces of the board.
