Overview: This product is made by our company with well-known institutions of higher learning long-term research and development of proprietary products for the current worldwide resistance to salt spray for copper passivation has been no lack of long points, breaking the current market of traditional recipes, bold never We had the synthesis of new materials, new technology. Currently in copper passivation has reached world advanced level. With a chromic acid, and benzene handle system unparalleled tradition passivation effect. For copper after chemical polishing, electrolytic polishing, mechanical polishing and other surface treatment, immediately passivation, the active metal surface is converted to inert metal surface, can effectively prevent the oxidation of copper surface, maintain the character after polishing. Suitable material: Suitable for all copper and copper alloy materials. Kai Union brand a strong advantage of copper passivation solution :: 1, patented formula, patented product, the market of traditional products can not match. February and simple operation, without complex equipment, room temperature can be used. 3, efficient: the passivation time is short, and high efficiency. 4, the high degree of oxidation gasification, salt spray test better than chromated. 5, safety and environmental protection, without containing harmful substances, odorless, water-based products. Usage: 1, all kinds of polished copper after polishing with this solution immediately (because copper oxide in a natural environment very fast, within a few hours to oxidation discoloration), clean polished, put soaked in this liquid for 8 minutes. 2, after time out, rinse with water. 3, drying packaging (recommended drying temperature should not exceed 60 degrees, preferably natural temperature "wind" dry), high temperature copper will turn yellow.
