Sodium dichromate (Aqueous Solution): chemical resistance of ASP floors
How each ASP epoxy and polyurethane flooring product performed when fully immersed in sodium dichromate (aqueous solution), from ASP's chemical resistance guides (December 2022).
Summary33% at 20°C: excellent for ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS and ASP-screedSTB.
33% at 20°C: excellent for ASP-creteSL, ASP-creteMD, ASP-creteRT and ASP-creteVS.

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.
