Sherwin M535 provides anti-corrosive protection when applied onto blast cleaned steel. Formulated to be used in situations where coal tar pitch products are excluded on health and safety grounds, or where bleed through of pitch into topcoats is not acceptable.
Recommended application via airless spray, roller or brush for small areas and touch up only. Recommended thinner cleanser no9. Recommended Primers: Macropoxy L574 Blast Primer, Macropoxy L425, Macropoxy C425V2. Blast clean to Sa2½ BS EN ISO 8501-1:2007. Average surface profile in the range 50-75 microns.
Manually prepared surfaces should be prepared to a minimum standard of St3 BS EN ISO 8501-1:2007 at the time of coating. Ensure surfaces to be coated are clean, dry and free from all surface contamination. May also be applied over a wide range of pre-fabrication primers, including inorganic zinc silicate and epoxy types. Indefinitely overcoatable by itself or by a wide range of anti-fouling compositions.
Where this material is used as a touch-up primer on ships bottom systems, care must be exercised to keep overlap of the primer onto existing coatings to a minimum. The nature of solvents in this material may cause some shrinking and crazing of certain anti-fouling coatings if excessive overlap occurs. This effect is purely cosmetic and will not affect the corrosion resistance of the overall system, however careful supervision and application will reduce the effect to a minimum.
A high build, 2 pack epoxy, zinc phosphate primer / buildcoat for the anti corrosive protection of steel.
Used as a temporary protective coating for steel surfaces prepared by abrasive blast cleaning.
