Styrene: chemical resistance of ASP floors

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

SummaryAt 20–25°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 styrene

Which ASP floors resist styrene (at 20–25°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 styrene?

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

Is polyurethane flooring resistant to styrene?

Some ASP polyurethane systems are rated excellent for styrene at at 20–25°C.
