Description

Sherwin-Williams Zinc Clad M501 is a 2-pack epoxy zinc rich anti-corrosive primer, providing anti-corrosive protection of steel surfaces prepared by abrasive blast cleaning. It may also be used as a repair primer for galvanized surfaces.

Endorsements

  • Meets the performance requirements of ISO20340 (2009) as part of a three coat system
  • Conforms to composition and performance requirements of Norsok M501 Rev.5 (2004) System 1
  • HA Item No 109 

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. 

Surface Preparations

Blast clean to Sa21⁄2 BS EN ISO 8501-1:2007 (SSPC-SP10/ NACE2) Average surface profile 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 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 Size: 0.38mm (15 thou)
Fan Angle: 20-30°
Operating Pressure: 115kg/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.

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 significantly 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.
