Key Advantages
This product is suitable for oxide removal from common copper products such as red copper and brass. Its oxide-removal speed is comparable to that of hydrogen-peroxide-type copper polishing agents, while the brightness after polishing is lower than that of hexavalent-chromium-type and hydrogen-peroxide-type products.
It contains no heavy metals such as hexavalent chromium, does not generate toxic nitrogen oxides, is more environmentally friendly, and complies with RoHS standards.
It contains no hydrogen peroxide, making operation and storage safe. The chemical solution is stable and does not decompose, and the package will not swell.
Degreasing components are added, so slight oil contamination on the copper workpiece surface will not affect use.
