EXPANDABLE POWDER COATING COMPOSITION, METHOD OF COATING A SUBSTRATE WITH HEAT-INSULATING FOAM AND COMPOSITE MATERIAL OBTAINED THEREBY Abstract An expandable, powder coating composition is disclosed which comprises (a) a thermoplastic resin containing a hydroxyl group-containing polymer, (b) a cross-linking agent containing a polyisocyanate compound which is capable of reacting with the hydroxyl groups of the polymer to crosslink the polymer at a temperature higher than the melting point of the thermoplastic resin and which is solid at room temperature, and (c) a blowing agent capable of decomposing and generating a gas when heated to a temperature higher than the melting point of the thermoplastic resin. Powder coating with the coating composition can give a heat-insulating, foamed sheath or lining over the surface of a metal tube or box to be used in air conditioners.
