NCL Epoxy M306 is a two part, low viscosity epoxy resin for sealing of fine cracks and repairing of cracked concrete to restore the structural strength. The cured NCL Epoxy M306 entirely and completely restores the concrete to its original monolithic conditions. NCL Epoxy M306 is supplied in two bulk containers for use together with two-component injection machine or pressure grout pump.
AREAS OF APPLICATION
Mixing Proportion (A:B): 2 : 1
Mixed Viscosity (PaS) at 25ºC: Approximately 800 cps
Pot Life at 20ºC: Approximately 60 minutes
Cure Time at 20 – 25º C: Minimum 24 hours
NCL Epoxy M306 system cured for 7 days at 20ºC has the following properties :-
Tensile Strength (ASTM C 307): 22 N/mm²
Compressive Strength (BS 6319): 60-80 N/mm²
Tensile Strength in Flexure (Din 1164): 30-50 N/mm²
Peel Strength (Din 53282): 4 – 7 N/mm²
Water Absorption (DIN 53475): 20 mg
Providing the cracks to be injected are not too fine, blow them out with compressed air to remove all dusts. Make sure the compressed air is free from oil and water.
After the cracks have been cleaned, bond flanged injection nipples onto the surface with adhesive. Ensure that the nipples are not blocked with the adhesive used. Dry all wet surfaces before applying the adhesive.
The recommended distance between any two injection points should be between 20cm to 50cm depending on the thickness of concrete structure. Place the injection nipple onto the concrete surface that was cracked all the way through.
Seal the cracked surface between the injection nipples with adhesive. Cracks through the entire thickness of concrete structure should be sealed on both sides.
Resin M306 (Part A): 20 Litre (Clear Colour)
Hardener M306 (Part B): 10 Litre (Amber Colour)
CLEANING OF TOOLS
Tools and equipment should be cleaned with solvent immediately after use.
One year when stored in a well-sealed container.
