Concrete substrate, medium consisting of 30% hydrofluoric acid and 20% nitric acid, maximum temperature of 80 degrees. What kind of coating or anti-corrosion layer, or other protective methods can be used to solve this problem?

I’m not sure if epoxy resin will work

Conventional epoxy resins and coatings can withstand temperatures up to 80 degrees, but this is under conditions free from acids and bases. In the presence of inorganic acids, some acids with a certain concentration can only be used for extended periods at 50 degrees Celsius.

In such operating conditions, polyurea coatings have poor corrosion resistance.
