Your cart is empty.You are buying 10 Ounces (by weight) of Printed Circuit Board Etchant. The item is in an 8 Fluid Ounce (by volume) Polypropylene bottle. The active ingredient in our Etchant is Ammonium Persulfate ((NH4)2S2O8). SUGGESTED USE Mix with water to make your own etching solution. 4 Ounces makes 16 Fluid Ounces (448 mL) of Solution. 16 Fluid Ounces of Solution etches 280 square inches of circuit board. This etchant remains transparent as it dissolves the copper from the board so you can monitor the etching process (unlike Ferric Chloride solution, which turns black). No heating or agitation required. Etching time is 5-15 minutes at room temperature. Spent solution can be neutralized with Baking Soda (Sodium Bicarbonate). The spent solution contains Copper Sulfate. Bottles are made of sturdy polypropylene. The square, “space-saver” shape ensures that the bottles fit snugly on a shelf. The wide mouth makes for easy dispensing and stackability. To ensure a spill-free journey, the screw tops are heat-sealed and the bottles are sealed in plastic.

Pros: doesn't stain, no smell, easy to store because it is dry, easy to mix.Cons: slightly slower to etch than what I used to use (ferric chloride or muriatic acid/peroxide) but definitely works.

The solution was weak. Wasn't etching at the rate listed on the bottle. I thought this would be safer to ship and more effective. I thought wrong.

The product was shipped and arrived promptly and it worked very well, alil on the slow for the process to complete a board on the smaller side aprox. 1"x1¾". How ever I did it at night outside so it could have been the temp being on the cooler side.
