Low temperature baking type electroplating varnish
Low-temperature baking type electroplating varnish is widely used in the plating surface of various products for maintenance.
Precautions
Coating on the coating, including coating and other thin organic maintenance films. More typical is the anti-tarnish treatment of silver plating, such as maintenance by electrophoretic coating, which is now commonly used in the musical instrument industry. Silver plating is also commonly used in organic solvent maintenance layers, such as BY-2, DJB-823, TX anti-silver coloring agent, etc., which can form a solid film on the surface of the silver plating layer, so as to shield the corrosive medium and avoid discoloration.
