EPF337 Winter-grade Epoxy Topcoat is an epoxy coating used as a topcoat. It is particularly suitable for maintenance coating of cargo holds, decks, hulls or ballast tanks, with low surface preparation, low-temperature application and curing, and excellent abrasion resistance, anti-corrosion performance and chemical splash resistance. High-performance, two-component, winter-grade epoxy resin topcoat, in various colours. Parameters on this page: volume solids 56.5%, dry film thickness 50–80 µm depending on surface conditions, theoretical spreading rate 9.4 m²/kg.

New construction: apply a suitable anticorrosive primer before coating; the primer surface shall be kept clean, dry and free from contamination, and overcoated within the specified overcoating interval. Maintenance: corroded areas shall be surface-prepared and coated with a suitable primer; the whole surface shall be kept clean, dry and free from contamination, and this topcoat applied within the specified overcoating interval.
This product can cure at temperatures as low as -15 °C; however, during low-temperature application, ensure that no ice is present on the surface and that the substrate surface temperature is at least 3 °C above the dew point.
