Instructions for use:

Mixing ratio by volume: base to hardener 80:20

  • The temperature of the mixed base and hardener should preferably be above 15°C, otherwise extra solvent may be required to obtain application viscosity
  • Too much solvent results in reduced sag resistance
  • Thinner should be added after mixing the components.

Induction time: 20 minutes if applied at temperatures below 10°C. None above 10°C.

Pot life: 4 hours at °C
