Abstract
An expandable, powder coating composition is disclosed which comprises (a) a thermoplastic resin containing a copolymer of ethylene with vinyl acetate, (b) a cross-linking agent containing an organic peroxide, (c) a blowing agent, and (d) an organic plasticizer. Powder coating of a surface of a tube or box to be used in air conditioners with the coating composition can give a heat-insulating, foamed sheath or lining over the surface.
