POWER CLEAN CU-20

POWER CLEAN CU-20 is a copper sealer used for passivation after cleaning with POWER CLEAN DE-34, locking in the restored finish and holding off re-oxidation. Typical applications are copper passivation, post-brightening sealing and finish preservation.

Compatibility is confirmed against your actual components before anything is recommended. As a rule, alkaline grades suit steel and cast iron, while aluminium, zinc, brass and mixed-metal baskets need a neutral-pH grade such as POWER CLEAN NF-14.

Power Clean aqueous concentrates work between 1% and 5% — that is 1:100 to 5:100 with water. Light maintenance soils sit at the low end; heavy machining oil, buffing compound and carbon need the upper end. The exact figure is set during the trial on your own parts.

55–65 °C for most aqueous grades. That is also where low-foam products stop foaming, because their surfactant clouds out just below the working range. A trichloroethylene vapour degreaser, by comparison, has to be held at 90–100 °C.

20 L, 50 L, 200 L and 1000 L, with custom packing available. Every product ships with a safety data sheet plus dosing and PPE guidance, and production runs to an ISO 9001 certified system with batch-wise quality control. Trials normally start with a single 20 L pail.
