Tetrahydronaphthalene: chemical resistance of ASP floors

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

SummaryAt 20–25°C: excellent for ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, 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 tetrahydronaphthalene

Which ASP floors resist tetrahydronaphthalene (at 20–25°C)?

Rated 5 (excellent, no significant deterioration after long-term contact): ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, ASP-creteSL, ASP-creteMD, ASP-creteRT and ASP-creteVS. Not resistant (0): ASP-coatWBE.

Is epoxy flooring resistant to tetrahydronaphthalene?

Some ASP epoxy systems are rated excellent for tetrahydronaphthalene at at 20–25°C. Check the exact concentration and temperature in the table, as ratings change with both.

Is polyurethane flooring resistant to tetrahydronaphthalene?

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