Copper anti-discoloration agent MS0423 offers free samples 0: 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 no lack of long points, break through the current market traditional recipes, there has never been a bold synthesis of new materials and new technology. Currently in copper passivation has reached the world advanced level. With a chromic acid, and benzene handle traditional system passivation unparalleled results. For after copper chemical polishing, electrolytic polishing, mechanical polishing and other surface treatment, immediately passivation, the surface layer is converted to the active metal inert to the metal surface, can effectively prevent the oxidation of copper surface, maintain the character after polishing. Suitable materials: suitable for all copper and copper alloys. I. Introduction: This product is also known as an anti-oxidant copper or copper deactivator. Able within five minutes of rapid oxidation resistance in the copper surface passivation film good, keep copper pieces stored indoors over a year does not change color. Because this product is environmentally friendly synthesis of heterocyclic organic compounds, non-toxic rot, chromic acid and nitrite-free and other harmful substances, biological degradation, making it ideal for high environmental requirements environments. Second, the product advantages: 1. Cost Economy: per kilogram medicine can handle 30 ~ 50m2 surface area, the share of low cost; 2. convenient and efficient: water-based products, film five minutes fast, easy to use; 3. ability to prevent discoloration Strong: copper indoor storage for one year does not change color; 4. non-toxic and environmentally friendly: no heavy metals, RoHS compliant, biodegradable; Third, use: after cleaning the copper pieces immersed in this anti-discoloration agent, soak at room temperature 5 to 30 minutes (the longer the better) after removing, rinse with water after drying or dry clean can be, when dry can not overlap between the workpiece, the drying temperature is recommended not to exceed 80 ℃. If you can be directly used for inter-process rust long soak in this solution. Note 1 against discoloration before cleaning or pickling process must be cleaned, and ongoing treatment after anti-tarnish treatment when necessary, in order to avoid contamination of the product; 2 anti-color treatment process for inter-if, based on cost considerations According to the actual situation of the goods can be 1: 1 to 2 with water use; four, the great advantage of Kai Union brand copper passivation solution :: 1, patented formula, patented product, the market of traditional products can not match. 2, between the simple operation, without complex equipment, can be used at room temperature. 3, efficient: passivation time is short, and high efficiency. 4, the high degree of oxidation gasification, salt spray test is better than chromate passivation. 5, safety and environmental protection, without containing harmful substances, odorless, water-based products. V. Kay League for you to solve the problem: First, do not need professional equipment, no professional staff, to complete two simple soaking, no complicated process requirements Third, you can re-use, low-cost four, environmentally friendly, safe operation, Six absolutely no odor, Kay Union Service: We will delivery technicians come to guide the operation of seven, Kay National League divisions: Chongqing, Dongguan, Zhongshan, Foshan, Suzhou, Ningbo, Taizhou
