    • Good color and gloss retention
    • Cures at temperatures down to -5°C (23°F)
    • Resistant to splash of mineral and vegetable oils, paraffins, aliphatic petroleum products and mild chemicals
    • Can be recoated even after long atmospheric exposure
    • Good application properties

    Recommended Substrate Conditions and Temperatures

    Substrate conditions

    • Previous coat (epoxy or polyurethane) must be dry and free from any contamination
    • Previous coat: surface should be sufficiently roughened if necessary

    Substrate temperature and application conditions

    • Substrate temperature during application at -5°C (23°F) is acceptable; provided the substrate is free from ice and dry
    • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
    • Relative humidity during application and curing should not exceed 85%
    • Should condensation on the surface occur during, or soon after application, this could result in color and gloss change

    Instructions For Use

    Mixing ratio by volume: base to hardener 88:12

    • The temperature of the mixed base and hardener should be above 10°C (50°F), otherwise extra thinner may be required to
      obtain application viscosity
    • Thinner should be added after mixing the components
    • Adding too much thinner results in reduced sag resistance
