    Recommended Film Thicknesses & Theoretical Coverage



    Recommended film thicknessesTheoretical coverage
    WetDry
    75µm40µm13.0 m²/l
    155µm80µm6.5 m²/l

    Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.



    Drying Times

    Dust dry, after50 minutes20 minutes10 minutes5 minutes
    Touch dry, after2 hours1 hours30 minutes15 minutes
    Recoatable, after5 hours3 hours1 hours30 minutes

    Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.



    Surface Preparation


    • Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

    Steel surfaces:

    • Blast clean to grade Sa2½. (ISO 8501-1)
    • In order to get the best performance the surface profile should be medium grit. (ISO 8503-2)



    Recommended Topcoats




    Application Conditions


    • All surfaces must be clean, dry and free from contamination.
    • The temperature of the ambient air, surface and paint should not fall below 5ºC during application and drying.
    • Relative humidity of the air should not exceed 80% during application and drying.
    • The surface temperature of steel should remain at least 3°C above the dew point.
    • Good ventilation and sufficient air movement is required in confined areas during application and drying.

    Note! There is a natural tendency of this coating to chalk, discolour or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical requirements on colour appearance.



    Mixing Components


    • First stir base and hardener separately.
    • The correct proportions of base and hardener must be mixed thoroughly before use.
    • Use power mixer for mixing.
    • Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface and weaken the properties of the coating.

    Application


    For airless spraying:

    • The product is thinned depending on the temperature of the components and shape of the object approximately 0–5%.
    • Recommended nozzle tip is 0.015"–0.021" and pressure 120–180 bar.
    • Spray angle shall be chosen according to the shape of the object.

    For brush application:

    • Product should be thinned according to the circumstances.
    • Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by brush before the spray application.
