Pure water for a perfect powder coat
Powder coating is going green. In some cases this is the result of legislation which requires existing process cleaning solutions to be replaced with more environmentally friendly ones. Increasingly, however, it’s coating quality that is the driver. Some coating specifications now demand salt spray testing for more than 1000 hours, and that means that surface preparation is absolutely critical. One of the proven ways of achieving high quality surface preparation is the use of pure water. Mains water contains a wide range of dissolved salts. These are harmless in drinking water but can promote corrosion and poor adhesion of powders to metal surfaces.
