  • Suitable for atmospheric industrial and marine applications
  • Can be recoated with various two-component and conventional coatings, even after long weathering periods
  • Lead- and chromate free
  • Excellent rust preventing properties in industrial or coastal atmospheres
  • Tough, with long-term flexibility
  • Cures even at temperatures down to -10°C (14°F)
  • Good adhesion to steel, galvanized steel and aged epoxy coatings
  • Easy application, both by airless spray and brush
  • Can be used as epoxy primer/finish (for dry internal areas)

RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

  • Substrate conditions
  • Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)
  • Shop primed steel; pretreated to SPSS-Pt3 / SSPC-SP3
  • Galvanized steel must be sweep blasted until an even flat appearance (only for internal dry exposure conditions)
  • Aged suitable coating must be dry and free from any contamination
  • Substrate temperature
  • Substrate temperature during application and curing down to -10°C (14°F) is acceptable; provided the substrate is free from ice and dry
  • Substrate temperature during application should be at least 3°C (5°F) above dew point
  • Relative humidity during application and curing should not exceed 95%

INSTRUCTIONS FOR USE

Mixing ratio by volume: base to hardener 82:18

  • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Adding too much thinner results in reduced sag resistance and slower cure
  • Thinner should be added after mixing the components
