Surface Preparation


Apply only on a clean and dry surface with a temperature above the dew point to avoid condensation. In confined spaces, provide adequate ventilation during application and drying.

Steel (Blast Cleaned):

  • Blast clean to ISO 8501-1 SA 2.5 with a blast profile of maximum 35-65 µm Rz
  • Remove abrasive residues and dust from the surface
  • Apply 4-0490 as soon as possible after surface preparation to prevent any contamination.
  • Do not leave blasted steel overnight



Mixing


  • Thoroughly mix paint before activating and check colour before use

Mixing & Application Procedure

It is important to follow this procedure carefully:

  • Flush equipment thoroughly using clean solvent
  • Stir primer to an even consistency with a power stirrer
  • Add hardener to primer and continue stirring for 5 minutes
  • Strain through a 60 mesh filter to prevent possible clogging of equipment
  • Thinning is not normally required for airless application
    • Up to 20% thinner may be added for workability
    • Stir during application to maintain uniformity of the material
    • Overlap each pass 50% to avoid bare areas, pinholes or sags
  • Double coat all welds, rough spots, sharp edges and corners, rivets bolts etc
  • Application at 120 microns wet film thickness will normally provide a dry film thickness of 75 microns
    • Avoid excessive film builds which can lead to cohesive failure
  • Check thickness of dry coating, and if less than specified, apply additional material as needed
  • Small damaged areas may be touched up by brush
    • Large areas by spray application
  • In confined areas, ventilate with clean air during the application and drying processes until all solvents are removed
    • The temperature and humidity of the ventilating air must be such that moisture condensation will not form on the primer surface
  • Clean all application equipment immediately after use, or at least at the end of each working day

 

Application By Conventional Or Pressure Pot

  • This material may be applied by conventional spray gun or pressure pot by adding 15 – 20% thinner 1-410 or 1-400
  • Separate air and fluid pressure regulators, mechanical pot agitator and a moisture / oil trap in the main compressed air supply line are recommended
  • Large fluid tips – 2.0 / 2.2mm will be needed

 

Brush/Roller Application

  • Suitable for small areas only, such as touch-up, repairs and stripe coating
