Sherwin-Williams Macropoxy C425V2
Sherwin-Williams Macropoxy C425V2 (formerly 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. Network Rail and NORSOK approved, ideal for use in internal/external exposed conditions including offshore, petrochemical and sub-sea environments.
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.

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.
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.
It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
