Substrate moisture content
≤ 4 % parts by weight
The following test methods can be used: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Pot life
Temperature | Pot life |
+25 °C | ~60 minutes (100 g mass) |
+55 °C | ~30 minutes (100 g mass) |
The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5 °C).
Open time
Temperature | Open time |
+25 °C | ~80 minutes (100 g mass) |
+55 °C | ~50 minutes (100 g mass) |
Consumption
Consumption will depend on the roughness of the substrate and the type of reinforcement to be bonded. See respective Sika® CarboDur® Product Data Sheet and also refer to:
- Method Statement: Sika® CarboDur® Externally Bonded Reinforcement - Ref 850 41 05
- Method Statement: Sika® CarboDur® Near Surface Mounted Reinforcement - Ref 850 41 07
SUBSTRATE QUALITY
Substrates must be structurally sound and of sufficient tensile strength to provide a minimum pull off strength of 1.5 N/mm2 or as required in the design specification.
Reference must be made to the Sika Method Statements:
- Method Statement: Sika® CarboDur® Externally Bonded Reinforcement - Ref 850 41 05
- Method Statement: Sika® CarboDur® Near Surface Mounted Reinforcement - Ref 850 41 07
SUBSTRATE PREPARATION

MIXING
IMPORTANT
Mix full units only.
IMPORTANT
Over mixing must be avoided to minimise air entrainment.
Note: Always use a mixing spindle attached to a slow speed electric drill (< 300 rpm).
- Add Part B (hardener) to Part A (resin).
- Mix Parts A+B continuously for ~3 minutes until a uniformly coloured mix is achieved.
- To ensure thorough mixing, pour materials into a clean container and mix again for approximately 1 minute.
APPLICATION
