Basic Data At 20 °c

( For mixed product )
Mass density
approx. 1.4g/cm3
Solids content
approx. 53% by volume
Recommended
dry film thickness
35 μm
Theoretical
15.1 m2/ltr for 35 μm*
spreading rate
depending on the nature and condition of the substrate and the
application method employed
Touch dry after
approx. 30 minutes
Overcoating interval
min. 16 hours*
max. 10 days*
Full cure after
7 days*
Shelf life (cool,dry place)
12 months
Flashpoint
base 17 °C – hardener 26 °C

– substrate must be dry and free from any contamination
– steel: blast cleaned (dry or wet), to ISO-Sa2½
– shop primed steel: pretreated according to SPSS Pt3
– concrete: remove all laitance and loose material
– must not be applied at temperatures below 5 °C
– substrate temperature should be at least 3 °C above the dew point

– mixing ratio: by volume; base to hardener 75 : 25
– 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
none
Potlife at 20 °C
10 hours
