Sherwin-Williams Macropoxy C400W (formerly known as Epigrip C400W) is a multi-functional epoxy zinc phosphate coating specified for use as a primer on blast cleaned structural steel for internal and external environments. Sherwin-Williams Macropoxy C400W may also be used as a high build intermediate coat as well as the final coat where a low sheen industrial and functional finish is required (not for immersion service).
Specified for use as a primer for structural steel on blast cleaned steel for internal and external environments, it may also be used as a high build intermediate coat as well as the final coat where a low sheen industrial and functional finish is required.
Not for immersion service.
Where good colour and gloss retention is required in an external environment, or a full decorative finish is required in an internal environment, one of our topcoats designed specifically for this role should be chosen. A selection of available topcoats is listed in this data sheet under Recommended Topcoats.
C400W may be applied between 75 and 275 microns DFT in one coat depending on specification requirement.
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 @ 23°C and will vary with temperature.
Application Conditions & Overcoating
This material should preferably be applied at temperatures in excess of 5oC. Relative humidity should not exceed 90% and in these conditions good ventilation is essential.
Substrate temperature shall be at least 3oC above the dew point and always above 0°C.
In order to achieve optimum water and chemical resistance, temperature needs to be maintained above 5oC during curing.

Please can you confirm the likely thickness of paint if applied with brush/roller. Thanks
Answer from Rawlins’ Technical Team:
Practical application rates for brush in microns are dry - 65 wet - 94.
Practical application rates for roller in microns are dry - 60 wet - 87.
