CONDUCTIVE RESIN FOR POWDER COATING PROCESSES |

 GE Plastics has announced a line of conductive Noryl GTX resins that are optimized for powder coating. The materials contain conductive fillers that eliminate the need to apply an electrostatic primer.
Because the materials were designed for powder coating operations,
conductive Noryl GTX resins can replace metal substrates, offering
increased design freedom and eliminating costly and potentially
hazardous chemical pre-treatments, the company says. Also, the Noryl
resin grades make it possible to powder-coat metal and plastic on the
same production line for economies of scale and uniform aesthetics.
Conductive Noryl GTX resin, a blend of polyamide (PA) with modified
polyphenylene ether (MPPE), is reinforced with conductive filler
packages to ensure electrostatic adhesion of the powder coating. In
addition, it is said to be a high performance material that can
withstand the curing temperatures of current powder coating processes.
Unlike conventional plastics that must be coated with an electrostatic
primer, or metals that must be chemically pre-treated to remove grease,
the resin requires only a washing step prior to beginning the powder
coating process.
The resin should soon be certified as a GE
ecomagination product, following a rigorous analysis that quantifies
environmental and operating benefits to customers in a transparent
process, which is audited by a third party. GE's ecomagination
initiative is a major worldwide initiative to increase research and
development in environmental technologies; drive new business
opportunities by helping customers solve their toughest environmental
challenges; reduce the company's greenhouse gas emissions; and increase
energy efficiency.
