Copper Cleaner & Brightener SQ-TQX700

SQ-TQX700 is an eco-friendly copper polishing and cleaning agent. It eliminates the need for traditional "triple-acid" polishing formulas—containing no nitric acid and producing no yellow nitrogen oxide fumes. The solution is highly stable and designed for use via a room-temperature immersion process. It offers rapid polishing without the risk of over-corrosion, leaving copper components looking bright and brand-new. Furthermore, it is simple to use and cost-effective.

PRODUCT DETAILS

This product adopts dipping treatment, and the process flow is polishing → washing → fixing → washing → washing → drying; the polishing process directly uses the original solution, the applicable temperature is 10~40℃, and the processing time is 20~60 seconds. The fixing process is based on a 1:1 ratio of chemicals and water, and soaking at room temperature for 30 seconds. After the bath liquid is consumed and copper ions are enriched during continuous production, the solution can be cooled to remove copper sulfate crystals, and a small amount of sodium nitrate can be added for continued use. When the oil stain on the workpiece is seriously oxidized, it is necessary to remove the oil in advance. Turn the workpiece during processing to avoid stacking. After polishing, wash it thoroughly and then fix the color to prevent oxidation and discoloration of the copper parts. The product is a light yellow transparent liquid, 25 kg/barrel, stored in a cool and dry place.
