What it is and what it does. Copper polishing agent QLQ-011 is the additive that improves the levelling and the brightness of acid copper deposits, and it produces the polished look used on hardware that is copper plated for its own colour.
- Pale yellow to amber clear liquid, dosed from a dilute stock solution in small amounts.
- Acts on the growth of the copper crystal, which is what creates the levelling effect over a fine scratch pattern.
- QLQ supplies the matched make-up and maintenance additions.

Buyer Questions We Answer Every Week
| Question | Answer |
|---|---|
| Why is the deposit cloudy after a top-up? | Probably an overdose; the usual correction is a carbon treatment and re-balancing. |

Buying questions we answer most
Is the SDS available before we order?
Yes. SDS and COA are issued per lot. Tell us the destination country so the SDS is supplied in the required format and language.
Can we get a trial quantity first?
Yes. Trial packs are quoted separately and shipped with the analytical method, so your lab can verify the material against the current bath before switching.
What packing and shelf life should we expect?
Standard export packing in drums or jerry cans with inner liner. Shelf life depends on the product - typically 12 months in a closed container, stored away from heat and direct sunlight.
How is it shipped - is it dangerous goods?
Some products are classed as dangerous goods and need the correct UN packing and documentation. We confirm the classification and the shipping route before quoting freight.
Can you match a competitor's additive?
Send the TDS and a bath sample. We compare the operating window and analytical method, then run a Hull cell panel before recommending a replacement.
