Surface preparation
  • Surface should be clean, dry, and free of dirt, rust, oil, soluble salt or water, grease, wax, loose paint, and any other contaminants.
  • We recommend a minimum commercial preparation such as SSPC-SP-2 or SSPC-SP3.
  • SSPC-SP-6  standard sandblast would be much more appropriate and strongly recommended for better corrosion resistance.
  • Surface temperature must be at least 3oC higher to the dew point temperature in order to avoid condensation.
  • Hardener: 611-000B (regular) & 611-001B (anti-sagg)
  • Mix 4 parts by volume of A and 1 part by volume of B.

IMPORTANT: Mix mechanically in order to obtain a homogeneous product


  • Conventional air spray
  • Airless, air assisted, air mix.
  • Electrostatic version (contact your representative).
  • Paint brush for hardly accessible places.


For conventional equipment:

  • Reduce the material with thinner to a viscosity of 20-25 sec FC#4 before applying.
  • Pressure at gun should be approximately 40-50 PSI and 10-15 PSI in pressure tank.


For "airless" equipment:

  • Reduce the material with thinner to a viscosity of 25-35 sec FC#4 before applying.

Consult your local sales representative for information about the application.

  • Do not leave the paint in the hose, guns and pump. The equipment has to be well cleaned with Sunamco cleaning thinner Sunaclean 100-113.
  • For drying time exceeding 24 hours we recommend a light sanding for a better inter-coat adhesion.
  • Make sure you complete the profile sandblasting in order to avoid surface rust caused by an angular profile.


Due to the wide variety of substrates, surface preparation methods, application methods, and environment, users should test the complete system for adhesion and compatibility under their conditions prior to starting their production.

N.B. To make adhesion, hardness, flexibility, impact test, or any other test, it is recommended to wait 7 daysat 25ºC (68ºF) and 50% humidity to enable the chemical reaction to be completed. If conditions are not fits outlined, the reaction time could be longer.

  • Do not apply at temperatures below 10oC or 50o F otherwise drying and the hardness will be affected.
  • As with most epoxy coatings, when there is no topcoat, the 603 line may chalk or discolour when exposed to ultraviolet outside light.  On the other hand, this does not affect the anticorrosive properties of this product.
  • This product must be used in a well ventilated area.
  • Before using this product, please consult MSDS label and Technical Data Sheet.
