| Abstract: |
The present invention provides a method for coating a substrate with a thermoplastic polymeric powder, especially polyester powder, by forming an emulsion containing fine particles of such powder, applying the emulsion to the substrate, and heating the coated substrate to a temperature sufficiently high to evaporate the liquid from the emulsion and thermally bond the particles to the substrate. The emulsifying agents are fatty acid esters of glycerol. |
