The California Air Resources Board has announced its approval of Hunter Chemical Fume Control HCA-8.4 for use in decorative chrome plating and chromic acid anodizing operations located in California. Given the strict nature of California air quality regulations, this is seen as a significant step in broader approval of the compound. Hunter Chemical is a supplier of PFOS-free (perfluorooctane sulfonate) fume suppressants.  Formulations HCA-8.1 and HCA-8.2 are in widespread use across the US, as the industry has transitioned away from PFOS-based compounds over the past couple of years.  HCA-8.1 and 8.2 offer a way to manage the changes associated with EPA regulations by lowering surface tension and helping to lower chromium emissions in anodizing, decorative and hard chrome applications.  HCA-8.4 will also be made available for use in all markets, both in the US and internationally. The company is an ISO9001:2008 certified supplier of nickel, cobalt and chrome based chemicals, shipping from multiple warehouses across the US and Canada.
