Supply of environmental common copper protective agent, high temperature resistant to salt spray

IWG - XPOO22 copper protection Introduction: IWG-XPOO22 copper protection is an organic protective film without heavy metals, environmental pollution, is environmentally friendly products, can effectively prevent metal oxidation. This protective film 260 ℃ baking temperature, by 72 hours salt spray (NSS) test, and does not affect the plating efficiency and weldability of the workpiece. For copper layer general oxidation treatment, with less cost savings. Weak acid leaching to remove this protective film for the protection of copper alloys, copper, bronze, imitation gold, rose gold, nickel, chrome and other metal surfaces. Operating conditions: Operating Range concentrate: 0.5% to 10% (according to the claimed select the appropriate concentration of about 100 square meters per liter protect) Temperature: 30 ~ 40 ° C (for the nickel plating layer 35-40 ° C) Time: 20 to 120 seconds (according to the protection requirements, and select the appropriate time) for: mechanical agitation filtration: filtration cycle (when the surface water film rupture phenomenon does not occur, with the need to protect the new solution)
