Copper Passivation Liquid
Product Overview:
Environmentally friendly copper alloy passivation liquid adopts international leading R&D technology specifically for copper and The environmentally friendly, chromium-free passivation solution developed for copper alloy products has a weakly alkaline formula that is suitable for passivation and anti-rust treatment of various types of copper materials. The salt spray resistance test lasts for a long time without affecting the conductive properties. It is the final corrosion inhibitor and anti-corrosion agent for copper products during the process. Best choice for rust.
Second product advantage:
. Suitable for corrosion prevention and rust prevention of copper, purple steel, white copper, bronze, brass and other workpieces between processes or final products.
. Ultra-long anti-salt spray and anti-rust performance (according to - and neutral salt spray test standards and above, initial rust spots will begin to appear, but the anti-corrosion effect may vary due to different material characteristics) The effect is better when used with copper polishing products .
. After passivation, the surface appearance, color, gloss, size, etc. of the workpiece will not be changed and the conductive properties of the product will not be affected.
. Environmentally friendly, chromium-free, non-toxic, in line with the latest EU standards and does not contain hexavalent chromium components such as chromate.
. High water ratio can be diluted ~ times, long service life, simple operation, easy to use and soak at room temperature.
Three recommended uses:
. Widely used in precision electronics, precision instruments, aerospace, mobile communications, chassis cabinets, power copper bars, crystal oscillators and other fields.
. Applied to copper sheets, copper tubes, power copper bars, crystal oscillators, precision terminals and other products.
Four environmental protection performance:
. It does not contain harmful substances and complies with r, r environmental protection standards and has passed the testing. The wastewater will be discharged after treatment and will have no impact on the environment.
5. Packaging and storage:
. This product is packaged in plastic barrels (kg/barrel).
. Store in a ventilated, cool and dry place. The storage temperature does not exceed ℃ and avoid direct sunlight. The validity period is 3 months.
