Introduction: This product is also known as anti-oxidants or copper copper anti-discoloration agent can in the 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, as the product is environmentally friendly synthesis of heterocyclic organic compounds, non-toxic rot, does not contain harmful substances such as chromic acid and nitrous acid, a biodegradable performance, making it ideal for environmentally demanding environments. Second, the product advantages: 1, the cost of the economy: the surface area per kilogram medicine can handle 30 ~ 50m2, the share of low cost. 2, convenient and efficient: water-based products, film five minutes fast, easy to use. 3, anti-color capability: copper indoor storage for one year does not change color. 4, non-toxic and environmentally friendly: no heavy metals, RoHS standard, readily biodegradable. Third, use: after cleaning copper pieces immersed in this anti-discoloration agent, room temperature water for 5 to 30 minutes (the longer the better) after removing, rinse with water after drying or to dry clean, not overlap between the workpiece when dry, drying temperature is not recommended to exceed 80 ℃. If you can be directly used for inter-process rust long soak in this solution. Fourth, note an anti-discoloration before cleaning or pickling must be done before the treatment process, and ongoing treatment after anti-tarnish treatment when necessary, in order to avoid contamination of the product. 2 If treatment process used to prevent discoloration between cost considerations based on the actual situation of the goods can be 1: 1 to 2 with water.
