    Application Equipment


    The following is a guide. Changes in pressures and tip sizes may be needed for proper spray characteristics.

    Always purge spray equipment before use with listed reducer.

    Any reduction must be compliant with existing VOC regulations and compatible with the existing environmental and application conditions.

    Airless Spray:
    Nozzle Size0.38mm (15 thou)
    Fan Angle20-30°
    Operating Pressure115kg/cm 2 (1600 psi)

    The airless spray details given above are intended as a guide only.

    Details such as fluid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen.

    However, the operating pressure should be the lowest possible consistent with satisfactory atomisation. As conditions will vary from job to job, it is the applicators' responsibility to ensure that the equipment in use has been set up to give the best results.



    Recommended Topcoat


    Indefinitely overcoatable with epoxy systems provided a minimum of 60 microns (2.5 mils) dft is obtained.

    Do not overcoat with paints containing saponifiable resins such as oleo-resinous or alkyd based paints unless a non-saponifiable resin based barrier coat has been applied first.



    Additional Notes


    Drying times, curing times and pot life should be considered as a guide only.

    The curing reaction of epoxies commences immediately the two components are mixed, and since the reaction is dependent on temperature, the curing time and pot life will be approximately halved by a 10°C/50°F increase in temperature and doubled by a 10°C/50°F decrease in temperature.

    Exposure to Weathering

    If Zinc Clad IV EU is exposed to the weather, there is a risk of the formation of zinc salts on the surface, which must be removed by fl ash blasting or washing down prior to overcoating, otherwise intercoat adhesion may be adversely affected.

    The rate of zinc salt formation will vary from one location to another. Under severe conditions e.g. marine coastal, offshore or heavy industrial areas, it is strongly recommended that overcoating takes place within 7 days.

    Epoxy Coatings - Tropical Use

    Epoxy paints at the time of mixing should not exceed a temperature of 35°C/95°F. At this temperature the pot life will be approximately halved. Use of these products outside of the pot life may result in inferior adhesion properties even if the materials appear fit for application. Thinning the mixed product will not alleviate this problem.

    The maximum air and substrate temperature for application is 50°C/122°F providing conditions allow satisfactory application and film formation. If the air and substrate temperatures exceed 50°C/122°F and epoxy coatings are applied under these conditions, paint fi lm defects such as dry spray, bubbling and pinholing etc. can occur within the coating.

    Numerical values quoted for physical data may vary slightly from batch to batch.



    Clean Up Instructions


    Clean spills and spatters immediately with Thinner No.5. Clean tools immediately after use with Thinner No.5. Follow manufacturer's safety recommendations when using any solvent.



    Surface Preparation


    Blast clean to Sa2½ BS EN ISO 8501-1:2007 (SSPC-SP10/ NACE2) Average surface profi le in the range 50 - 75 microns (2.3 mills).

    Ensure surfaces to be coated are clean, dry and free from all surface contamination.

    For repair of galvanizing, for small areas, abrade the surface to a minimum standard of St3 BS EN ISO 8501-1:2007 (SSPC-SP3) feathering off the edges of intact galvanizing surrounding such areas, and then brush apply the primer. For large areas it is recommended that the surface is flash blasted.



    Application Conditions


    Epoxy paints should preferably be applied at temperatures in excess of 10ºC/50°F. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3ºC/37°F above the dew point and always above 0°C/32°F.

    At application temperatures below 10°C/50°F, drying and curing times will be signifi cantly extended, and spraying characteristics may be impaired.

    Application at ambient air temperatures below 5°C/41°F is not recommended.

    In order to achieve optimum water and chemical resistance, temperature needs to be maintained above 10ºC/50°F during curing.
