Grey/reddish grey two component Zinc Rich Epoxy Primer with outstanding resistance to severe weathering.
- For use on structural steel, machinery, pipe and tank exteriors & general maintenance
- The high zinc content of the primer film gives a cathodic protection if the film is damaged, as it combines the toughness of an epoxy with the superior protection of zinc
- Product can be purchased as a Two Component Pack, or as Base or Hardener only
- As part of a Selemix system it provides superior performance in a wide range of corrosive environments
- With suitable topcoats it withstands splash/spillage of water, solvents, chemicals & petroleum products
- For Industrial Use Only

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

Please Note: Refer to the Product Data Sheet for detailed information regarding mixing ratios for the relevant binder/base and hardener/activator used.
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
