Pyridine Bases: chemical resistance of ASP floors
How each ASP epoxy and polyurethane flooring product performed when fully immersed in pyridine bases, from ASP's chemical resistance guides (December 2022).
SummaryAt 20–25°C: no product rated excellent; not resistant: ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB and 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 pyridine bases
Which ASP floors resist pyridine bases (at 20–25°C)?
Not resistant (0): ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB and ASP-coatWBE.
Is epoxy flooring resistant to pyridine bases?
ASP's epoxy products are not rated excellent for pyridine bases at the tested conditions. Check the table for shorter-term ratings, or consider the polyurethane or vinyl ester ranges.
Is polyurethane flooring resistant to pyridine bases?
ASP's polyurethane products are not rated excellent for pyridine bases at the tested conditions. Check the table for shorter-term ratings, or ask about vinyl ester systems.
