Description

PPG AquaCover 400 (also known as Sigma Aquacover 400) is a two-component, polyamine-cured, waterborne epoxy coating for steel structures in atmospheric exposure. Touch dry in 90 minutes, the coating is free from lead- and chromate-containing pigments, making it particularly suitable when solvents are not permitted because of health and safety reasons. Can be overcoated with most dispersion and alkyd paints, and 2-component durable finishes.

Also suitable for concrete floors.



Top Features & Benefits


  • Free from lead- and chromate-containing pigments
  • Can be overcoated with most dispersion and alkyd paints, and two-component durable finishes
  • Easy application by brush/roller and (airless) spray
  • Semi-gloss finish

Preparation & Application


Recommended Substrate Conditions & Temperatures


Substrate conditions

  • Steel with suitable primer must be dry and free from any contamination within the recoat times
  • Galvanized surfaces are variable and the preferred method of treatment is to lightly sweep blast followed by degreasing and cleaning
  • Concrete; surface must be cured, clean, dry and free of desintegrated or chalky materials

 

Substrate Temperature & Application Conditions


  • Substrate temperature during application and curing should be above 10°C (50°F)
  • 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 75%

 

Instructions For Use


Mixing ratio by volume: base to hardener 70:30

  • Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434)
  • Too much water results in reduced sag resistance and slower cure
  • Must be protected from freezing at all times during storage and/or transport
  • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Water should be added after mixing the components

 

Application


 

Air spray


Recommended Thinner

  • Tap water

Volume of thinner

  • 0 - 5%, depending on required thickness and application conditions

Nozzle orifice

  • Approx. 0.48 mm (0.019 in)

Nozzle pressure

  • 15.0 MPa (approx. 150 bar; 2176 p.s.i.)

Cleaning solvent


Cleaning procedures

  • Pulsator filter and tip filter must be taken out of the equipment and cleaned properly
  • The following tables illustrate the cleaning procedure of the spray equipment when changing from spraying with solventborne paint to waterborne paints (table 1) and from waterborne paints to solvent-borne paints (table 2)
