Notes:

  • See below for more information on surface preparation, application details and curing times

Surface Preparation


Recommended Substrate Conditions and Temperatures

Substrate conditions

  • Previous coat (epoxy or polyurethane) must be dry and free from any contamination
  • Surface of previous coat should be sufficiently roughened if necessary

 

Substrate Temperature & Application Conditions


  • 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 85%

Application


Instructions for Use

Mixing ratio by volume: base to hardener 83:17

  • 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
  • Thinner should be added after mixing the components
  • Adding too much thinner results in reduced sag resistance

 

Induction Time


None.

 

Pot life


  • 5 hours at 20°C (68°F)

Refer below for more information

Notes:

  • Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS
  • Safe Working in Confined Spaces (1433) and Directives for Ventilation Practice (1434)
  • Should condensation on the surface occur during, or soon after application, this could result in gloss reduction

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 vapour, as well as contact between the wet paint and exposed skin or eyes
  • Contains a toxic polyisocyanate curing agent
  • Avoid at all times inhalation of aerosol spray mist
