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 five 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 serious discolor
