Boric Acid: chemical resistance of ASP floors
How each ASP epoxy and polyurethane flooring product performed when fully immersed in boric acid, from ASP's chemical resistance guides (December 2022).
Summary20% at 20°C: excellent for ASP-creteSL, ASP-creteMD, ASP-creteRT and ASP-creteVS; not resistant: ASP-coatWBE.

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 boric acid
Which ASP floors resist boric acid (20% at 20°C)?
Rated 5 (excellent, no significant deterioration after long-term contact): ASP-creteSL, ASP-creteMD, ASP-creteRT and ASP-creteVS. Not resistant (0): ASP-coatWBE.
Is epoxy flooring resistant to boric acid?
ASP's epoxy products are not rated excellent for boric 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 boric acid?
Some ASP polyurethane systems are rated excellent for boric acid at 20% at 20°C.
