Product Features and Benefits

  • General-purpose epoxy coating in protective coating systems for the protection of steel structures in atmospheric exposure
  • Good adhesion to steel
  • Good flow and wetting properties
  • Easy application by airless spray
  • Cures at temperatures down to 5°C (41°F)
  • Good performance on top of zinc silicate primers
  • Colours available: Redbrown, Cream, Grey
  • Eggshell finish

 

Method of Application

  • Airless spray
  • Brush/Roller

Note:

  • Application by brush may show brush marking, due to the thixatropic nature of the paint and is most suitable to small areas, tight angle areas or for stripe coating or touch-up
  • Application by roller will leave roller marking and is suitable for minimum DFT requirements only
  • A roller suitable for epoxy application must be used
  • Adequate ventilation must be maintained during application and curing (please refer to sheet 1433 and 1434)

Please refer to the product Data Sheet for further surface preparation, mixing and application instructions.

 

Overcoating

  • PPG SigmaCover 246 has an unlimited overcoating interval provided the surface is free from chalking and other contaminations
  • In cases of exposure to direct sunlight or when the surface is contaminated it is recommended that the surface be cleaned and roughened to ensure good adhesion of the subsequent coating
  • The optimum intercoat adhesion is obtained when the subsequent coating is applied before the full cure time of the previous coating has elapsed
