Jesse Zhu, Ph.D., and Hui Zhang, Ph.D. September 2005, p. 39. An ultrafine powder technology has been developed by our research group that allows the complete fluidization of ultrafine par- ticles down to nanometer size. Using this technology, powder coatings with average particle sizes between 10.0 microns and 20.0 microns have been successfully applied in production settings, producing highqual- ity surface finishing comparable with the liquid coatings used for automobile exteri- ors. Compared with standard powder coat- ings, the new ultrafine powder coatings reduce surface roughness 80 to 90 percent and cut powder use 25 to 50 percent, while maintaining the same surface protection. This article explains this new powder coat- ing technology. Powder coating conductive high-heat- resistant plastic parts on the same line with metal parts. Iain Montgomery. March 2007, p. 15. Plastics are used for a variety of parts from mobile telephones to automotive body pan- els. However, powder coating has not been the finish of choice primarily because of the challenges involved in the non-conductiv- ity and temperature resistance of these materials. That is about to change. This article discusses a new plastic resin that is not only conductive, but also heat resistant to more than 400 degrees F. The article discusses how this development will now allow powder coaters to finish both plastic and metal parts on the same line. Metallic powder coating for aluminum wheels. Kazuhiro Hatano, Seiji Hibi, and Masahiro Nakamura. March 2008, p. 20. From the viewpoint of measures for envi- ronmental issues, the amount of solvents in paint for aluminum wheels needs to be minimized. Environmentally friendly powder coatings have been used widely for primer coating and clear coating, but there is no precedent for its use for base coating. This time, we optimized the condition of the surface treatment of the pigment and the hardening behavior of the constituent resin in the melting process and succeeded in developing a metallic powder coating for aluminum wheels that fulfills the appearance and the quality requirements of aluminum wheels. Thin powder color topcoat: Powder coating process for small parts in bulk production. Dan Riter. March 2010 digital issue, p. 14. This article describes a powder coating process applicable to many types of fasteners and small parts called Thin Powder Color Topcoat (TPCT). These coatings are applied to metal parts, with or without a base coating, in an innovative bulk pro- duction process that incorporates a proven thermal diffusion coating method. The article explains how the new process is suit- able for mass finishing of small- and medium-size parts with powder coatings, providing substantial cost savings when compared with rack or spray coating. Test results indicate positive outcomes on a wide range of materials, showing excep- tional durability and versatility in control- ling the uniformity, thickness, and colors available for small parts production. Metallic powder coatings: Advance- ments in chrome effects. William Pofahl. March 2011 digital issue, p. 16. Powder coating systems offer several advantages when compared with tradi- tional liquid paint systems. Besides their obvious environmental advantage, powder coatings offer economic and quality advantages over their liquid counterparts. The range of effects allowed by powder coatings includes metallics, such as the metallic effects created by use of aluminum pigments. However, to date the industry hasn't created a metallic effect in a powder coating system that truly replicates the visual appearance of traditional chrome plating. This article outlines the methods used to create metallic effects, emphasizing chrome, and introduces a new chrome effect powder coating system. The article also provides relevant background on this sector of the powder coating market. Powder coating durability and the pass- ing of Canada's stringent environmental law in 2010 drive business boost at Ontario auto-body shop. Peggy Wright. (Pelletier's Auto Body & Pow- der Coating, Thunder Bay, Ont.) March 2011 digital issue, p. 21. While striving to leave the lightest foot- print on the environment and protecting employees, an Ontario autobody shop uses its staff's extensive training and experience to wow manufacturing clients with the quality and durability of powder coating. Automotive industry rally boosts pow- der coating use. March 2012 digital issue, p. 14. General Motors Co. and Daimler Trucks North America rev up production, creat- ing jobs and boosting profits that help other industries, including the powder coating industry. Infrared curing Near-infrared curing: What it is; what it isn't. Mike Stuhldreher. November 2002, p. 25. The powder coating industry continues to grow, thanks to advances in technology that range from new formulations for raw materials to improved application meth- ods. In addition, the industry has pro- gressed by finding new ways of using exist- ing technology or by adapting technology already being used in other industries. This is the case with near infrared (NIR) curing. Although it shares some character- istics of conventional infrared (IR) curing Index to Articles and Authors Suggested Reading ARTICLE INDEX
