Curing Compound TM AC-1 is a curing compound for concrete and consists of emulsified acrylic resin. A thin film is generated on the surfaces after Curing Compound TM AC-1 has been applied. This film keeps the water needed for cement hydration in the concrete. Curing concrete with Curing Compound TM AC-1 is necessary to prevent shrinkage caused by fast drying because this could result in the formation of surfaces cracks.
