eRC120.jpg (80515 bytes)


RC120 is a solvent-free epoxy resin compound specially formulated for the repair of faulty concrete, curing at low temperature and high humidity.  The cured resin exhibit several outstanding properties, such as high mechanical strength, excellent adhesion to a wide range of substrates, outstanding resistance against water and chemicals, negligible shringkage, etc.

fixing anchorage for machinery in the concrete and rock.


Heavy duty and chemical resistant flooring.


Concrete crack repairs by V-cut method.


Abrasive and waterproofing coating to a wide range of substrates.

Application notes

  1. Correct mixing ratio and thorough mixing are important for complete chemical reaction of two components.
  2. The surface of application must be structurally sound, clean and free of grease.
  3. The mechanical property is greatly determined by the compaction during the curing process of the epoxy/sand mortar


Properly stored indoor with ventilation, avoiding direct sunlight and heat. Shelf life is 12 months.
