PPG - Sigmadur 550 - Polyurethane Paint for Steel is a two-component, aliphatic acrylic polyurethane finish with excellent resistance to atmospheric exposure conditions that cures at temperatures down to -5°C (23°F).

Features

  • Unlimited recoatable
  • Excellent resistance to atmospheric exposure conditions
  • 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
