ABSTRACT:
Conductive polymer sheathed polymeric particulate powders comprise a polymeric core powder; and from about 5 to about 30 percent by weight of an intrinsically conductive polymer forming a sheath around the core powder. A method of providing corrosion protection to metal substrates comprises applying a conductive polymer sheathed polymeric particulate powder to a metal substrate to form a coating at least about 0.5 mils thick; wherein the conductive powder comprises a polymeric core powder; and from about 5 to about 30 percent by weight of an intrinsically conductive polymer forming a sheath around the core powder, the resulting conductive polymer powder having a particle size greater than about 1 micron.
