Sherwin-Williams Macropoxy C425V2 (formerly known as Epigrip C425V2) is a high build 2-pack epoxy zinc phosphate primer/buildcoat to provide anti-corrosive protection of carbon steel surfaces prepared by abrasive blast cleaning.
Sherwin-Williams Macropoxy C425V2 can be spray applied at thicknesses between 100 and 250 microns dry to provide both primer and buildcoat in a single coat.
A top coat is only required for decorative purposes. Without topcoat, Sherwin-Williams Epigrip C425V2 will quickly discolour and patchiness may be exaggerated due to film thickness variation, but will nonetheless provide excellent anti-corrosive protection as a single coat protective epoxy nor will intercoat adhesion be affected by any discolouration.
Sherwin-Williams Macopoxy C425V2 is for use in internal/external exposed conditions including offshore, petrochemical and sub-sea environments.
- Network Rail – Item No 7.1.4
- Complies with BS5493:1977 - Table 4K Type KP1A.

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.
For overcoating outside the above parameters and with alkyd systems, consult our Technical team.
Application Conditions & Overcoating
Epoxy paints should preferably be applied at temperatures in excess of 10ºC. 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.
At application temperatures below 10°C, drying and curing times will be signiﬁ cantly extended, and spraying characteristics may be impaired. Application at ambient air temperatures below 5°C is not recommended.
In order to achieve optimum water and chemical resistance, temperature needs to be maintained above 10ºC during curing.
