ABSTRACT:
A process of coating a substrate such as aluminum by the steps of (a) applying thereon a powder coating composition prepared by (i) blending a mix containing a poly(vinylidene fluoride) resin, a thermoplastic resin, a pigment, and a vinylidene fluoride/tetrafluoroethylene/hexafluoropropylene terpolymer, (ii) pelletizing the blend from (i), and (iii) cryogenically grinding the pellets from (ii); (b) heating the powder coating composition above its melt temperature; and (c) cooling the coated substrate.
