Perdure UMC SC/Primer is a urethane modified concrete primer/sealer. It bonds tenaciously to properly prepared substrates. It is used as primer and/or sealer over Perdure UMC TG or UMC SL systems. It also refinishes old and abused urethane concrete floors.
The Perdure UMC SC kit consists of polyurethane resin, resin hardener, and a blend of Portland cement and aggregates. A color pack is also included in the kit if requested.
As a primer, Perdure UMC SC reduces the potential for pinholes in various UMC systems. As a topcoat, it is suitable in heavy-duty applications such as restrooms/lockers, kitchens, cafeterias, equipment maintenance areas, laboratories, manufacturing facilities, processing areas, bottling/packaging areas, and other areas requiring a chemical resistant, sanitary, high impact, solid color finish.
