Ammonia (Aqueous Solution): chemical resistance of ASP floors

How each ASP epoxy and polyurethane flooring product performed when fully immersed in ammonia (aqueous solution), from ASP's chemical resistance guides (December 2022).

Summary10% at 20°C: no product rated excellent; 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 ammonia (aqueous solution)

Which ASP floors resist ammonia (aqueous solution) (10% at 20°C)?

Not resistant (0): ASP-coatWBE.

Is epoxy flooring resistant to ammonia (aqueous solution)?

ASP's epoxy products are not rated excellent for ammonia (aqueous solution) at the tested conditions. Check the table for shorter-term ratings, or consider the polyurethane or vinyl ester ranges.

Is polyurethane flooring resistant to ammonia (aqueous solution)?

ASP's polyurethane products are not rated excellent for ammonia (aqueous solution) at the tested conditions. Check the table for shorter-term ratings, or ask about vinyl ester systems.
