Hydrofluoric Acid: chemical resistance of ASP floors
How each ASP epoxy and polyurethane flooring product performed when fully immersed in hydrofluoric acid, from ASP's chemical resistance guides (December 2022).
Summary20% at 20°C: no product rated excellent; not resistant: ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, ASP-coatWBE, ASP-creteSL, ASP-creteMD, ASP-creteRT, ASP-creteVS and ASP-coatPU.

Ratings come from 30 × 30 mm samples cast at each product's prescribed thickness, cured for 7 days and fully submerged at 20–25°C. On a real floor, a spill only touches the surface, so performance is usually better. Elevated temperatures accelerate chemical attack. How to read these ratings.
Questions about hydrofluoric acid
Which ASP floors resist hydrofluoric acid (20% at 20°C)?
Not resistant (0): ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, ASP-coatWBE, ASP-creteSL, ASP-creteMD, ASP-creteRT, ASP-creteVS and ASP-coatPU.
Is epoxy flooring resistant to hydrofluoric acid?
ASP's epoxy products are not rated excellent for hydrofluoric acid at the tested conditions. Check the table for shorter-term ratings, or consider the polyurethane or vinyl ester ranges.
Is polyurethane flooring resistant to hydrofluoric acid?
ASP's polyurethane products are not rated excellent for hydrofluoric acid at the tested conditions. Check the table for shorter-term ratings, or ask about vinyl ester systems.
