    • PURPOSE: A liquid formaldehyde-free coating agent, its preparation method, a coated sound panel, its coating method and a formaldehyde-free coating composition are provided, to improve moisture-induced hanging resistance and to prevent the generation of an environment polluting material such as formaldehyde. CONSTITUTION: The liquid formaldehyde-free coating agent comprises an adhesive containing a crosslinked grid and a hydrophilic group chemically bonded to the grid; a compound having an elastic modulus of about 40-250 GPa; and optionally a filler. Preferably the crosslinked grid is selected from the group consisting of saturated or unsaturated polyester, polyurethane, polycarbonate, alkyd, polyamide, polyacrylate, polymethacrylate, epoxy, resin-phase polymer, maleic acid or its anhydride polymer and copolymer, ionomer, vinyl pyrrolidone polymer and copolymer, poly(vinyl alcohol) polymer and copolymer, hydrophilic graft-having polymer and copolymer, thermosetting resin, carbomer resin and their combinations. Preferably the hydrophilic group is selected from the group consisting of an ionic group, a neutral hydrophilic group and their combination.
