Metal coating to improve oxidation product is a special water-based sealant color, also known as protective agent, sealing agent. Metal coating process of the various factors plating (coating quality, coating thickness, porosity, etc.), the surface prone to discoloration of product features. This product can effectively improve the surface quality of metal plating, while the metal coating with corrosion protection. Are environmentally friendly products. 

 This is suitable for nickel, gold, tin coating oxidation discoloration, prolonged salt spray test time 1 to 2 times. Does not affect the surface properties [surface conductivity, welding, etc.] 

 Use conditions: 

 To clean the workpiece to be addressed, immersed in the sealant xl-501. Uniform jitter, protection after cleaning with pure water (over 40 ~ 50 ℃ hot water better), dehydrated dry.
