The company's products AOY-319 Application passivation of copper: Copper and copper alloy passivation. 

 Usage: paired with copper passivation liquid working solution, product as long as the passivation of copper at room temperature aqueous solution can be impregnated with a minute or two, the appearance can be maintained for long periods of copper color, no verdigris. 

 The role of passivation of copper leaching: in copper and copper alloys quickly form a dense surface oxide film and polymer adsorption of transparent film, cut off from oxygen in the air, water direct contact with the substrate, played rust, and strengthen the corrosion resistance of the workpiece.
