Copper deactivator MS0420 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 extracted from plant extracts using organic heterocycles main agent of a new environmentally friendly copper deactivator, translucent appearance of brown, rich smell of fresh herbs. This product can be one very strong binding force of chemical conversion composite film formed on the surface of the copper pieces, to effectively resist corrosion and oxidation. This product is particularly suitable for passivation antirust copper pieces. Compared with similar products MS0407, lower product cost, but slightly inferior corrosion resistance. Second, the product advantages: 1, environmental protection: absolutely free of chromic acid and nitrous 2, anti-salt spray is good: copper NSS test 32 hours does not change color; 3. Economy: reusable, cost only 40 anti-rust oil %. Third, use: after cleaning copper pieces soaked in copper passivating agent, removing more than 15 minutes at room temperature after soaking, rinse with clean, dry, or dry. Process is very simple. Fourth, the process; degreasing - Over Water - passive - over the water - over water - drying V. passivation effect: samples of copper, for example, data for reference only compare the contents of a 1: 1 nitric acid titration (S ) neutral salt spray test (h) indoor exposure (day) of the high-temperature oxidation process 45S 36 小时 180 days of mild discoloration does not change color discoloration 180 ℃ 20min chromated 12S 8 小时 severe discoloration slight discoloration 15 days 180 ℃ 5min Six severe discoloration, 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. Seven, Kai Union 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, environmental protection, safe operation, Eight absolutely no odor, Kay Union Service: We will delivery technicians come to guide the operation of nine, Kay National League divisions: Chongqing, Dongguan, Zhongshan, Foshan, Suzhou, Ningbo, Taizhou
