Product Data


Recommended Substrate Conditions and Temperatures

  • Approved primer must be sound, dry and free from any contamination
  • Substrate temperature during application and curing should be between 5°C (41°F) and 40°C (104°F)
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
  • Ambient temperature during application and curing should be between 5°C (41°F) and 40°C (104°F)
  • Relative humidity during application and curing should not exceed 85%

 

Instructions for Use

  • Stir thoroughly until homogeneous and free of lumps
  • Adding too much thinner results in reduced sag resistance and slower cure

 

Airless Spray

Recommended thinner: PPG Thinner 21-06 (normally no thinner required)

Volume of thinner: 0 - 5%

Nozzle angle: 20° – 50°, depending on shape of steel parts

Nozzle orifice: Approx. 0.48 – 0.64 mm (0.019 – 0.025 in)

Nozzle pressure: 20.0 MPa (approx. 200 bar; 2901 p.s.i.)

 

Notes: All filters, including surge bottle and gun filters to be removed. External fluid uptake pipe filter is recommended

 

Brush/Roller
