471CN
Hempel's Epoxy MIO 471CN is a two-component, high-solids, low-VOC epoxy MIO high-build coating forming a hard film, pigmented with micaceous iron oxide to enhance the barrier effect.
As a primer or intermediate coat in a coating system, for protection of steel structures in atmospheric environments. Can also be used in systems requiring low-VOC or high-build anticorrosive coatings. Can be applied directly over cured zinc silicate or zinc-sprayed surfaces to minimise bubbling.

Nozzle pressure: 25 MPa
Orifice size: 0.48–0.64 mm. If using brush or roller, multiple coats are required to achieve the specified dry film thickness. Do not thin components separately – thin after mixing. Extra thinning may be required to reduce dry spray at high temperature. At low paint temperature, extra thinning may be required, which results in lower film build and slower drying. Spray parameters are indicative and may be adjusted to site conditions. Pressure values apply to material at 20 °C. (*For other application methods, consult the company representative!).

Depending on the application and area of use, the product may be specified at a film thickness different from that indicated. This changes the spreading rate, drying and curing times and overcoating intervals. For optimum performance, avoid excessive film thickness. Actual consumption factors may vary with application conditions, equipment and workmanship. Checking paint consumption against area improves film thickness control.
- If brush or roller application is used, more coats are required to achieve the specified dry film thickness.
For a more opaque and evenly formed film, first apply a mist coat, then after 2–15 minutes spray to the full film thickness.
