Electrolytic degreasing solution is used to activate any metallic substrate – surface before the real plating treatment. Basically, it is an alkaline solution that helps in both cleaning and preparation for the surface to be prepared. This process can be done in a wide temperature range generally between 25 and 50°C and by applying an electric tension of about 6 V by the usage of a stainless-steel anode as positive electrode. In this way the electrolytic process develops a high quantity of gaseous hydrogen bubbles that mechanically helps the whole preparation step.
