Epoxyden-wash primer is two a component Epoxy paint suitable, as a primer, for nonferrous metals such as Aluminum, Zinc (including galvanized steel) and their alloys. It is based on special resins and pigments providing excellent adhesion to the metals. Epoxyden wash-primer creates a strong basis, which is the first condition, for stable top painting.

 Properties

  • Excellent adhesion to: zinc (including galvanized steel), aluminum and their alloys without acids (which creates dangerous etching that if PH is not neutralize the remain acid prevents adhesion of top layer and/or burns the pigments of the top layer and shows stains like fade or make the paint peel)   .
  • A strong and durable primer for top paints.
  • It has excellent mechanical strength.
  • Resistant to scratches.
  • Resistant to diluted alkali or acids as well as to extreme humidity.
  • Durable for dry heat up to 200OC for short exposure time.
  • Suitable as primer paint for various top paints such as polyurethane, epoxy, chlorinated rubber, syntactic etc.
  • Easy to apply, dries quickly.
  • High coverage as a very thin layer needed.
  • Durable in fuels, oils, jet fuels etc.

Applications:

  • Primer paint for metals such Al, Zn (including galvanized steel) and their alloys
  • Primer paint for constructions made of galvanized steel, and elements from aluminum and galvanized steel in industrial uses.
  • Primer for aluminum and galvanized steel for aviation uses.

Surface preparation:

  • A thorough cleaning needed from dirt, dust and loose paints.
  • Galvanized steel – sand lightly to remove light oxidation and/or gloss and clean with air pressure, clean with dry clean cloth soaked with thinner/acetone.
  • Very old galvanization with rust – sand blast for total removing of rust.

Primer:

  • This product itself.

Top color:

  • You can paint the top layer 8-12 hours after painting the primer if it had the heat and dryness condition.
  • During the cold winter, you can paint only after 24 hours.
  • The top layer can be “Denbergloss”  aliphatic exterior polyurethane paint with UV resistance.

Instructions for use:

  • Open carefully parts A and B and stir separately.
  • Pour from two parts in the right ratio the required amount and mix well with mechanical mixer (operated by air pressure is recommended for safety reasons) for a uniform mixture.
  • Wait for 15 minutes while adding the thinner as needed and mix again. Spray a thin layer of at least 20 microns thickness dry film. If necessary if the layer does not completely uniform or part of surface not painted, wait about 4-12 hours for complete drying and spray another layer. Insert into clean and controlled temp. drying room for 12 hours before painting the top layer.
