Sherwin Williams Macropoxy M111 - Formerly Leighs Eprigrip is a 2 pack zinc phosphate epoxy wet blast primer for application to surfaces which have been prepared by wet abrasive blasting.
Macropoxy M111 is suitable for application to surfaces which have been prepared by wet abrasive blasting. May also be applied to grit blasted surfaces and for surfaces prepared by UHP water blasting where existing blast profile is exposed. Tolerant to application to surfaces which may be damp or wet at the time of application. An acceptable ‘ wet ‘ surface is defined as a surface on which a thin film of moisture is present, but is free from running water, droplets or pooled water.
Dry abrasive blast to Sa2½ BS EN ISO 8501-1:2007. Average surface profile in the range 50-75 microns. UHP or Aquagrit water blasted surfaces must also reveal an underlying surface equivalent to Standard Wa2½ (BS EN ISO 8501-4:2006). Light flash rust staining (as defined in Section 6 BS EN ISO 8501-4:2006) is acceptable provided it cannot be removed by rubbing. Manually prepared surfaces are acceptable for non-immersed situations and should be prepared to a minimum standard of ST3 BS EN ISO 8501-1:2007 and must be clean, dry and free from all surface contamination at the time of coating.
Recomended application method is via airless spray, conventional spray or brush. Recommended thinner Sherwin Williams Thinner No 5. Indefi nitely overcoatable with epoxy systems provided the surfaces to be coated have been suitably cleaned. Where a high degree of gloss and colour retention is required overcoat with Acrolon C137V2, Acrolon C237, Acrolon 1850 and Acrolon 7300 within 7 days at a minimum dft of 50 microns or in the case of Acrolon C750V2 overcoat within 4 days. These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.
