Copper anti-oxidants 
 A nature and function 

 Copper and copper alloy with good heat transfer, electrical conductivity, rolling and other physical and mechanical properties, but unstable and easily oxidized in air. Copper antioxidant antitarnish protective agent passivating agent processing can improve the copper and copper alloy corrosion, anti-discoloration, oxidation capacity, the surface can be formed passive film to prevent surface darkens, and the passivation does not affect the welding properties. 

 Two. Slotted and technology 

 Dosage: 3% (three-volume copper antioxidant antitarnish protective agent and a water purifier 97 volume) Time: 3-5min temperature of 20-50 ° C 

 Instructions for use: 

 Copper antioxidant antitarnish protective agent for copper polishing processing the last of the anti-oxidation process in the process, make the workpiece using the process of soaking agent and a little shake, so that the workpiece full access to the pharmacy. Copper antioxidant antitarnish protection agent odorless and easy to operate, high production efficiency. After the processing of the workpiece by the syrup must be approved by the water or pure water wash the surface, otherwise affect the workpiece surface. 

 Process: 

 Degreasing → washing plating or polishing → → washed 2 times → passivation → washing two times 

 Antioxidants is to prevent the copper oxidized in air color effects processing agent. 

 Applicable to copper, brass, copper alloy, acid copper, alkaline copper, copper alloy plating surface, neutral salt spray 24-48 hours. 


 Features: 1. Environmental protection, in line with EU standards. 

 Two. Water-soluble formulations, suitable with water treatment, especially for copper pickling passivation process. 

 3. Protective, long non-corrosive, do not fade. 

 4. Need a thorough water-based protective treatment will not cause the appearance of change and affect the conductivity, welding performance. 

 No watermark bad appearance. 

 Control convenience, room temperature operation, retirement or additional manifestly anti-discoloration to further strengthen the stability. 


 Use; 

 Immersion, brushing, spraying, etc. can be used to implement the corrosion protection of metal parts, also can be pipelined soak 
 And spraying manner the corrosion protection of metal parts. 


 General requirement is to clean the workpiece as the anti-color time at room temperature with anti-discoloration of water diluted solution so that 

 , The processing time for 10 minutes, and then water (preferably purified water), rinse clean and dry, drying dense 

 Sealed packaging can be. Anti-rust solution can be reused. 


 Note: 

 Clean, before using this, you want to workpiece surface rust, oil cleaning, so as not to affect the subsequent anti-corrosion effect. 

 Prohibited bare-hand handling, good workpiece by rust treatment, so as not to be printed on the fingerprint, hand sweat, and other pollutants affecting metal 
 Anti-corrosion effect. 

 3, the products do not have to be to be sealed well to avoid failure. 

 4, if accidentally splashed into the eyes can be filed eyelid, mobile water rinse. 

 5, can not eat this product, if swallowed, do not induce vomiting. Keep at rest, and timely health care. 


 Wastewater treatment: no effect on the environment, waste can be discharged directly. 

 Packaging and storage: 1 Packaging: 25kg / plastic barrel. 

 Storage: sealed and stored in a cool, dry and ventilated place.
