A powerful VOC vapor and moisture reducer, TOP SHELF® EPOXY CR-RESIN | MVR-FC is a high-performance, 100% solids epoxy system. This epoxy can be installed directly over slabs with a high risk of chemical vapor intrusion and extremely high moisture readings (25 lbs. MVER, 99% RH). The system is also one of the two Top Shelf® Epoxy systems with the highest chemical resistance, making it an excellent topcoat option as well.
