I recently changed one of my pages due to inaccurate information and also someone previously sent me an email asking how to make it as shown below:
“Hi Mr Eric. I saw your web page, and I need to learn how to make the cream formula. I know one of the chemical ingredients is HF, but I want to know in more detail what other materials are needed to mix until it becomes cream. That way the image looks more like ice snow.
Can you inform me?
Thank you for your attention and I hope to hear from you soon.”
I thought you should be aware of this as well, and you may have a similar question. See my answer below:
My page was actually incorrect before about the typical cream containing HF. Someone previously contacted me about it and I changed the site thanks to LeeAnn Higgins of the University of Minnesota Department of Biochemistry.
Although HF can be used for etching, it is very dangerous, and I don’t recommend using it. I have not seen any other brand use HF as an ingredient, but I haven’t researched all of them enough since I mainly use sandblasting techniques. The Armour Etch brand does not have any hydrofluoric acid in it as my page mistakenly stated before. You can see the MSD sheet here. The chemicals that make up the Armour Etch cream are:
- Barium Sulfate
- Sulfuric Acid
- Sodium Bifluoride
- and Ammonium Bifluoride
I hope this helps and if you have any other questions let me know.
