Basic Data At 20 °c

( For mixed product )
Mass density: approx. 1.4g/cm3
Solids content: approx. 53% by volume
Recommended dry film thickness: 50 – 100 μm
Theoretical spreading rate 6.6 m2/ltr for a dft of 80 μm*
depending on the nature, roughness and condition of the substrate and the application method employed
Touch dry after: approx. 3 hours
Overcoating interval: min. 10 hours* max. 3 months*
Full cure after: 7 days
Shelf life (cool,dry place): 12 months
Flashpoint: base 27 °C – hardener 28 °C

– previous coat of Sigma Floorguard Sealer or primer must be sound, dry and free from any contamination
– if previous coat is exposed longer it should be roughened prior
to application of next coat
– 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: 76 : 24
– the temperature of the mixed base and hardener should be above 15 °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: 10 minutes
Potlife at 20 °C: 8 hours
