About riag
Based in Wängi, Switzerland, riag Oberflächentechnik AG has been developing and producing a comprehensive range of chemicals for the chemical and electrochemical treatment of metals and plastics for over 30 years. The portfolio includes electroplating processes for zinc, tin, nickel, copper, silver and chromium, electroless nickel, electropolishing, conversion coatings and phosphating, as well as pretreatment, top-coats and demetallisation. In addition to the established standard programme, customised solutions for individual applications are developed. In the in-house laboratory, process chemicals and customer samples are analysed and tested; the company also offers chemical analyses, metallurgical investigations, consulting, training and system solutions for coating applications. According to its own statement, the company supplies customers in the surface technology, electroplating and coating industries worldwide.
