Questions & Answers
First and foremost, always add powder to water in small amounts because as it dissolves, a lot of heat is produced. This product is extremely soluble and absorbs water from the air; if left exposed to the air for an extended period of time, it will dissolve itself. The absolute maximum concentration is 98 grams per 100 ml of water (at 20 degrees Celsius). The definition of a "proper etchant" is a matter of personal preference, as there is a trade-off between etch speed and visibility/thickness. Aspects such as temperature and agitation are also important. To reduce undercuts on PCBs, a fast etch is required, and etch speed is limited. Because artists value visibility, their knife, gun, and other tools are frequently diluted up to four times. (400ml - 100g)
Hello, the first time I ordered the premixed liquid version, it was rejected by customs, but the second time I ordered the dry version, it went through without a hitch.
Adding 1 to a 45% solution yields a 45% solution. 8 oz. to 2 oz. water - Or 3. 6 oz. to 4 oz. 4 oz. bottled water
I do not know what the 2015% solution is all about. I am aware that this is a 4 oz bottle that yields 1 liter. As a result, 1 oz equals (1/4 Liter).

This worked perfectly for demonstrations with potassium thiocyanate. My trash can has turned a bloody hue, and it now resembles a crime scene.
It's what I use to etch my circuit boards. Clad in copper. All I need is a Sharpie Permanent ink pen. There will be no pens with special ink. After etching, I use alcohol to remove the ink. This was perfect for etching my boards. a businesslike appearance.
I used a small amount of it along with some water to burn out a broken titanium tap. It was very effective, but it took a few days to complete. Titanium was not harmed in the least. Given that I didn't have to remake the part, I'm very pleased.
It's just as it should be. You can make it as strong as you want with powdered ferric chloride. The label includes instructions. This is what I use to acid etch steel and do some of my titanium anodizing with.
This is what I use to etch PCBs and it works great. I'll have to dilute it with water in a 3:1 ratio. 1 to cut the time down to around 10 minutes.
The misspelled words on the label make it a bit sketchy, but it appears to work. But I'm not sure about what I actually bought. MSDS appears to be missing from the mix.
Great product that effortlessly etches the knives I make!.
It completed the task at hand.
