This product is the metal coating to improve the performance of special welding surface water sealer. As the plating metal plating process factors, when the surface of the solder resist welding prone to the phenomenon, affecting product functionality. It can be used effectively to improve the weldability of metal coating surface, while the metal coating with corrosion protection. Does not contain chromium and other harmful substances, an environmentally friendly product. 

 This product is suitable for general purpose metal flux protective coating. Significantly improved performance on the tin, does not affect the surface properties (appearance, conductivity and other properties)
