Product Description

Sherwin Williams Macropoxy C425V2 - Formerly Leighs Epigrip is a high build, 2 pack epoxy, zinc phosphate primer / buildcoat for the anti corrosive protection of steel.

Best Uses

Sherwin Williams Macropoxy C425V2 is formulated for use in internal/external exposed conditions including offshore, petrochemical and sub-sea environments for the anti corrosive protection of carbon steel surfaces prepared by abrasive blast cleaning.


Recommended application methods via airless spray, conventional spray, brush or roller. Recommended Thinner No 5 for thinning, or No 9 / No 13 for cleaning. Indefinitely 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.
