WPF1003 Waterborne Polyurethane Primer-Finish-In-One Coating is a waterborne coating. Used for corrosion protection of steel structure surfaces in light to severe atmospheric corrosive environments, widely used in marine facilities such as ships, containers, offshore oil platforms and docks, and in petrochemical, crude oil storage tanks, tank trucks, metallurgy, electric power and other industries. Contains no heavy metal pigments; environmentally friendly, flame-retardant, safe and easy to apply. Parameters on this page: dry film thickness 30-60 µm, theoretical spreading rate 11.04 m²/kg, number of components: two-component.

Primed or intermediate-coated surfaces shall be kept clean, dry and free from contamination; the substrate temperature shall be at least 3 °C above the dew point. The product cures down to 0 °C. When using, first stir the two components uniformly with a power stirrer, add 10% clean fresh water to thin, let stand for 10–15 minutes, then it is ready for use. Use within the pot life to avoid waste from gelling.
