PPG SigmaCover 690 is a two-component high solids, self-priming, low VOC, aluminium pigmented polyamine cured modified epoxy primer/coating.

 

Product Features and Benefits

  • Primer/coating designed for maintenance
  • Low VOC
  • Good flow properties
  • Self priming coating tolerant to lower grades of steel preparation
  • Compatible with most aged, good adhering coatings
  • Good recoatability with epoxy and polyurethane paints
  • Good curing at temperatures down to 5°C (41°F)
  • Good impact and abrasion resistance
  • If the substrate temperature drops below 5°C (41°F) until 0°C (32°F), the winter grade type should be used (see 7414WG)

 

 

Recommended Substrate Conditions and Temperatures

Atmospheric exposure conditions

  • Steel: blast cleaned to ISO-Sa2 or power tool cleaned to ISO-St2 for good corrosion protection
  • Steel with approved shop primer: sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt2
  • Existing sound coating systems: sufficiently roughened, dry and cleaned

 

Immersion in water

  • Steel: blast cleaned to ISO-Sa21⁄2
  • Steel with approved zinc silicate shop primer: sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt3

 

Substrate temperature

  • Substrate temperature during application and curing should be above 5°C (41°F)
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point

 

 

Application

  • Air Spray
  • Airless Spray
  • Brush/Roller

Please refer to Data Sheet for application instructions.
