ABSTRACT:
The metal platelets contained in a metal-containing powder coating composition may be oriented substantially parallel to a surface coated with this composition by the process herein described. This process comprises (a) coating the metal-containing powder coating composition on the surface, (b) heating the coated surface in order to melt the metal-containing powder coating composition, (c) simultaneous with the heating step, blowing a stream of hot fluid substantially parallel to the coated surface so as to orient the metal platelets substantially parallel to the surface, and (d) cooling the coated surface after the metal platelets have become oriented substantially parallel to the surface.
Contoured surfaces coated in accordance with this process have an appearance of depth similar to that obtained using a solvent system metallic paint.
