UNICOAT DWF A12 is a solvent-based, water-displacing fluid that results in a thin, waxy film rust preventive compound offering exceptional salt spray protection. DWF A12 works by displacing water from the metal and creating a protective barrier between the metal and the atmosphere.

DWF A12 has an oily layer of coating and therefore results in longer hours before failure under the ASTM B-117 Salt Spray testing. It offers medium-term protection of ferrous and aluminium alloy compounds during storage and transit and is particularly suitable for the protection of highly machined precision parts where heavy films are not desirable.

DWF A12 offers suitable protection for approximately 3 months of outdoor and 4 years of indoor storage. Protection length is dependent on weather conditions and storage location. Depending on the size of the type of workpiece to be treated, DWF A12 is recommended to be applied by dipping or brushing. The thin oily film does not hamper subsequent machining operations.
