## Description

Transparent solution allows visual inspection. Will not stain carpet or clothing. Compatible with etch resist pens. 1 kg of solid crystals makes 4 liters of solution. Ammonium Persulfate crystals are used as an alternative to the traditional ferric chloride to produce a cleaner copper etchant solution. Mixed product must be stored in a ventilated container. ROHS Compliant.

Review: This is significantly easier to use than ferric chloride, ... - This is significantly easier to use than ferric chloride, since this stuff is transparent, turns blue as it's used up and doesn't stain half my world yellow-brown. I etch at 50C, which tends to make the ammonium sulfate break down, but it gets the job done quickly and minimizes overetching and undercutting. Shelf life is an issue. I don't make pc boards very often, and my etchant tends to lose its potency after a few weeks in the bottle. I now make only a small batch (125 grams per 500 ml) and use a small (120 x 160 mm) glass tray to etch boards horizontally. I put the board on a perforated PVC shelf and agitate the solution with a magnetic stirrer. Works very well. The price has gone up 23% in 3 years, but the price with Prime shipping is hard to beat. I use a variety of MG Chemical products and have found them all to be consistently high quality.
Review: Good circuit board etchant - Needs to be heated to work, but is clear so you can see the etching progress.

## Questions & Answers

**Q: Is this pure ammonium persulfate?**
A: Yes, but it is not laboratory grade or purity.  It is industrial grade purity.  I have been using this product from MG to etch printed circuit boards since the 70's, and it is fabulous.

### ⭐⭐⭐⭐⭐ Great product!
*by W***Y on November 19, 2019*

Am a copper artist and use this for cleaning copper before applying a patina-I have about 40 different chemicals I use and create my own patina formulas. Been using this stuff for years-love it! No problems with the supplier.
