| Introduction
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.

Application notes
- Correct mixing ratio and thorough mixing are important for
complete chemical reaction of two components.
- The surface of application must be structurally sound,
clean and free of grease.
- The mechanical property is greatly determined by the
compaction during the curing process of the epoxy/sand mortar
Storage
Properly stored indoor with ventilation, avoiding direct
sunlight and heat. Shelf life is 12 months.
