Sherwin-Williams Macropoxy C400V3
Sherwin-Williams Macropoxy C400V3 multi-functional epoxy zinc phosphate coating is suitable for the protection of steelwork in a range of exposure environments from C1 to C5. It was recently used on The Shard for corrosion protection.

- Petrochemical plants
- Power stations
Macropoxy C400V3 Multi-functional Epoxy Coating (formerly known as Epigrip C400V3) is suitable for the protection of steelwork in a range of exposure environments from C1 to C5 as defined in ISO12944. Not for immersion service. Often 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.
All Epoxy products will lose gloss and colour when exposed in an external environment and so 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.
Macropoxy C400V3 may be applied between 75 and 275 microns DFT in one coat depending on specification requirement. As many projects will differ in terms of client requirements and exposure environments, detailed project specifications are available from our technical team separately.

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.
For overcoating with alkyd systems consult our Technical Team for advice. Overcoatable with Sher-Cryl M770 Water Based Finish within 1 month @ 15°C.
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.

Question: What is the best way to repair/repaint areas of primer damaged by rust etc
Blast clean to Sa2½ BS EN ISO 8501-1:2007. Average surface profile in the range 50-75 microns. Ensure surfaces to be coated are clean, dry and free from all surface contamination. Manually prepared surfaces should be prepared to a minimum standard of St3 BS EN ISO 8501-1:2007 at the time of coating. Application to such surfaces should be by brush or roller where the mechanical action will aid adhesion.

Question: I have lads working / mixing the C400v3 with a hardener additive.
I know that the mix is 7/1, but what is the working time once this is mixed, the working temperature is approximately 11/12c ?
Also, should a face mask be donned when applying this product ??
Once correctly mixed you will have an approximate pot life of 2.5 hours @ 15°C. Consult Product Health and Safety Data Sheet for information on safe storage, handling and application of this product which is available to download from the 'DATASHEETS' tab on this product page.
