Sherwin Williams Zinc Clad IV EU Formerly M501 is best used as a 2 pack epoxy zinc rich anti corrosive primer for the protection of steel surfaces. Also suitable as a repair primer for galvanised surfaces.
Apply using airless spray or brush for small areas and touch up. Blast clean to Sa2½ 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 surfaceto 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.
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. Indefinitely overcoatable with epoxy systems provided a minimum of 60 microns (2.5 mils) DFT is obtained.
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.
