Basic Data At 20 °c

( For mixed product )
Mass density: approx. 1.3g/cm3
Solids content: approx. 55% ±2 by volume
Recommended: dry film thickness 50 – 60 μm depending on system
Theoretical spreading rate: 11 m2/ltr for a dft of 50 μm*
depending on the nature, roughness and condition of the substrate and the application method employed
Touch dry after: approx. 1 hours
Overcoating interval: min. 6 hours* max. unlimited
Full cure after: 4 days
Shelf life (cool,dry place): 12 months
Flashpoint: base 27 °C – hardener 28 °C

– previous coat of Sigma Floorguard Coating, Flooring or Finish
must be sound, dry and free from any contamination and sufficiently roughened
– substrate and ambient temperature should be min. 10 oC and max.
30 oC during application and curing
– relative humidity should be not exceed 85%
– substrate temperature should be above 5 °C and at least 3 °C above the dew point

Mixing ratio: base : hardener by volume: 88 : 12
– the temperature of the mixed base and hardener should be above 10 °C, otherwise extra solvent may be required to obtain the correct application viscosity
– too much solvent will result in lower sag resistance and slower cure
– thinner should only be added after proper mixing of the base and hardener
Induction time at 20 °C: none
Potlife at 20 °C: 5 hours*
