169 brass sealer anti-discoloration agent protective agent copper plating protective agent

169 copper protective agent Help First, the nature and function of copper and copper-aluminum alloy has good heat conductivity, calendar and other physical and mechanical properties, but the air is unstable, easily oxidized. Use of the company's 169 passivating agent (also known as copper sealer, copper anti-discoloration agent, copper antioxidant,) treatment, to improve corrosion resistance of copper and copper-aluminum alloy, anti-discoloration, oxidation ability, the surface can be formed blunt film to prevent surface darkening and passivation does not affect the welding performance. Second, slotting and process Dosage: 3% (1 169 with 33 parts water) Time: 3-5min temperature 20-50 ℃ Third, the use of copper polishing passivating agent 169 processing the last of the anti-oxidation process, the use of process to make the workpiece immersed in Pharmacy and a little shaken, so that the workpiece full contact agents. The pharmaceutical odorless, easy operation, high production efficiency. But piece after syrup treatment, must be approved by surface water or washed with deionized water, or on the surface affected. Four process degreasing → washing twice → plating → washing or polishing twice → passivation → washing twice → drying (temperature should not exceed 100 degrees.) Note: If using a process fluid appears white cotton-like description of the concentration of suspended solids As long as appropriate to add water or high temperature can be solved, if not affect the appearance, but also as usual, will not affect the quality. Packaging: 25 liters / barrel Storage: Please put in a cool ventilated place, away from fire.
