Newswise — The North Dakota State University Research Foundation (NDSU/RF) announced today that it has concluded a license agreement with Elinor Specialty Coatings, Fargo, N.D., for a breakthrough hexavalent chromium-free coatings technology. The patented coatings technology protects aluminum alloys, such as those found in vehicle and ship parts, or in vehicles made entirely from aluminum.
The licensing agreement gives Elinor Specialty Coatings exclusive rights in marine and automotive markets to further develop and commercialize the patented coatings technology developed at North Dakota State University, Fargo.
The magnesium-rich technology will be used in primers marketed to both the military and civilian auto and shipbuilding industries under the trademarked names Aluma45-M™ and Aluma45-A™. According to Elinor Specialty Coatings, the coatings will provide viable alternatives in manufacturing and maintenance, without the toxicity of hexavalent chromium Cr(VI). The products are designed to be applied over chromium-free pre-treatments or bare metal, eliminating Cr(VI) entirely from the coating system.
Whether on vehicles or vessels, corrosion is a culprit costing companies substantial dollars. The toxic substance, hexavalent chromium Cr(VI)prevents corrosion, but can also contaminate the environment and contribute to cancer. People more commonly may be familiar with hexavalent chromium as featured prominently in the movie Erin Brockovich.
Elinor Specialty Coatings is the first and only company offering Mg-rich Aluma45-M™ and Aluma45-A™ in the marine and automotive markets. “The long-lasting protection allows longer periods between maintenance cycles, while eliminating the toxic work conditions and long-term hazmat storage dilemmas of Cr(VI) for companies or command units,” said Dante Battocchi, chief technical officer of Elinor Specialty Coatings.
Battocchi said previous chromate-free primers on the market did not provide the anti-corrosive properties of chromate, which despite its known toxicity, has not been banned in the U.S. because it is highly effective at inhibiting corrosion of high strength aluminum. The magnesium technology formulated for Aluma45-M™ and Aluma45-A™ at NDSU and now licensed by Elinor Specialty Coatings for marine and automotive use, provides the first non-chrome corrosion inhibiting system to perform as well as, or better than chromate in laboratory and field testing, according to Battocchi.
Potential benefits of the new technology include: reduced costs by eliminating the need for mandatory extra control measures designed to reduce exposure to chromate; and potential lower density than chromate primers, thus reducing weight and resulting in lower fuel consumption. According to Battocchi, many manufacturers currently rely on toxic coatings designed for steel, which aren’t nearly as effective on aluminum as the Aluma45™ primers.
“We are thrilled to see another more environmentally-friendly coating technology reach the market through Elinor Specialty Coatings,” said Dale Zetocha, executive director of the NDSU Research Foundation, which licenses technologies developed at North Dakota State University. “It represents a great opportunity to commercialize this coating technology research for these applications through a North Dakota company.”
North Dakota State University researchers playing a role in years of development of the patented Cr-free Mg-rich technology used in Aluma45-M™ and Aluma45-A™ include Dr. Gordon Bierwagen, Dr. Dante Battocchi, and Dr. Michael E. Nanna. Previous research funding that resulted in the development of these coatings was provided by the U.S. Air Force Office of Scientific Research; the Center for Surface Protection, a state Economic Development Center of Excellence at North Dakota State University; and the Product Design Center at NDSU.
