Surface Preparation


Recommended Substrate Conditions and Temperatures

Substrate conditions

  • Suitable primer must be dry and free from any contamination
  • When applied to zinc silicate, a mist coat and full coat technique is required

 

Substrate Temperature & Application Conditions


  • 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


Instructions for Use

Mixing ratio by volume: base to hardener 80:20 (4:1)

  • The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Adding too much thinner results in reduced sag resistance and slower cure
  • Thinner should be added after mixing the components

 

Induction Time


None.

 

Pot life


  • 6 hours at 20°C (68°F)

Refer below for more information

 

Air Spray


Recommended thinner

Volume of thinner

      • 0 - 10%, depending on required thickness and application conditions

Nozzle orifice

      • 1.7 – 2.0 mm (approx. 0.070 – 0.079 in)

Nozzle pressure

    • 0.3 - 0.4 MPa (approx. 3 - 4 bar; 44 - 58 p.s.i.)

 

Airless spray


Recommended thinner

  • THINNER 91-92

Volume of thinner

  • 0 - 10%, 30 - 40% when mist coat applied

Nozzle orifice

  • Approx. 0.46 – 0.53 mm (0.018 – 0.021 in)

Nozzle pressure

  • 20.0 - 25.0 MPa (approx. 200 - 250 bar; 2901 - 3626 p.s.i.)

 

Brush/roller


Recommended thinner

  • Application by brush may show brush marking, due to the thixotropic 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

Recommended thinner

  • THINNER 91-92

Volume of thinner

  • 0 – 5%

Maximum Extended Extended Extended Extended Extended

Notes:

  • This product has an unlimited overcoating interval provided the surface is free from chalking and other contaminations
  • The optimum intercoat adhesion is obtained when the subsequent coating is applied before the full cure time of the previous coating has elapsed
  • 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

 

Curing time for DFT up to 200 µm (8.0 mils)

Safety Precautions


  • For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
  • This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes
