Sherwin Williams Macropoxy C401 MIO Undercoat - Formerly Epigrip

Sherwin Williams Macropoxy C401 - Formerly Leighs Epigrip C401 is a 2 pack epoxy undercoat, pigmented with MIO (micaceous iron oxide).

Best Uses

Sherwin Williams Macropoxy C401 is formulated to work as an undercoat in conjunction with Sherwin Williams Epigrip high performance primers.

Application

Ensure surfaces to be coated are clean, dry and free from all surface contamination. Without topcoat, the material will quickly discolour and patchiness may be exaggerated due to film thickness variation, but will nonetheless provide corrosion protection as a single coat protective epoxy nor will intercoat adhesion be affected by any discolouration.

Can be applied using airless spray, conventional spray, brush or roller. Recommended Thinner Sherwin Williams No 5 for thinning and No 9 or No 13 for cleaning.

Recommended primers / topcoats Macropoxy C425V2, Macropoxy C400V3, Zinc Clad J984, Macropoxy C402V2. 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 d.f.t. of 50 microns or in the case of Acrolon C750V2 overcoat within 4 days. Epoxy paints should preferably be applied at temperatures in excess of 10°C. Relative humidity should not exceed 90% and in these conditions good ventilation is essential.
