Copper environmental chemical polishing agent MS0308 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 the current market traditional recipes, there has never been 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 based on our latest development of a new type of hydrogen peroxide and environmentally friendly brightener. Appearance colorless, non-toxic and tasteless. With the use of hydrogen peroxide for all copper and brass alloy chemical polishing. As the brightener with special stabilizer, stability of the working fluid several times better than similar products. Second, the product features: 1, temperature 80 degrees does not decompose 2, polishing step is completed, without retreat film, three simple steps, use: polishing liquid preheated to 40 to 45 degrees, polished container choose plastic or stainless steel container , copper and then put into a post-polishing cleaning solution, generally Brass Process 1 ~ 3min, copper surface to be treated 2-4min brown oxide film is formed after the removal, a simple rinsing with water and then put into a copper-containing sulfuric acid 5-8% sulfuric acid solution soak for a few seconds back film, and finally remove the workpiece can be washed subsequent processes. Stripping The process can be used without a brass polish. Fourth, the great advantage of Kai Union brand copper polishing 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
