MICRONICIDE PHP is a copper microetch based on Sulphuric Acid and Hydrogen Peroxide. MICRONICIDE PHP assures a perfect and uniform microetch of the copper surfaces with a constant etching rate and a low consumption of Hydrogen Peroxide. MICRONICIDE PHP has no chelating agents so it is easy to waste treat and remove the dissolved copper.
