Arkema has developed new manufacturing technology that allows it to stop using perfluorinated surfactants to make its Kynar 500 polyvinylidene fluoride (PVDF) metal coating resins in Calvert City, Ky. In a 2006 agreement with EPA, industrial users of perfluorinated surfactants, such as perfluorooctanoic acid, agreed to eliminate the suspected cancer-causing agents. 3M's Dyneon division recently said it was on track to complete such a switch for its fluoropolymer dispersions well ahead of the 2015 deadline set by EPA. Arkema says it now plans to use the Aquatec manufacturing technology at a PVDF coating resins plant to be built in Changshu, China.
