Patent ID: 6852790

Claim:
A method of electrostatic painting an article comprising forming an article comprising a conductive polymer composition and coating at least a portion of said article by electrostatic painting, wherein said conductive polymer composition comprises at least one polymer and at least one carbon black having an STSA of from about 10 to about 200 m 2 /g, an I 2 ZNo of from about 15 to about 250 mg/g, a tinting strength of about 130% or less, a DBPA of from about 20 to about 450 cc/100 g, a CDBP of from about 20 to about 400 cc/100 g, a ratio of I 2 No to STSA of from about 0.4 to about 2.5, a mean particle size of from about 14 to about 250 nm, and a % volatiles of less than about 1.0%, wherein the carbon black comprises from about 5 to about 40% by weight of the conductive polymer composition, and wherein the conductive polymer composition has a volume resistivity of greater than about 100 ohm-cm at room temperature.
