ABSTRACT:
A ferrous metal strip is provided with a wet film coating of a powder metal, powder refractory material or a mixture thereof dispersed in a resin binder composition formed of a synthetic organic resin and a volatile solvent, followed by heating the coated strip to remove the solvent and cure the organic resin. The metal strip with the cured resin-powder flexible non-tacky coating can be subjected to varying heat treatments to provide a wide range of protective coatings having improved surface properties. The formability properties of the cured resin-powder coating is further improved by applying a surface coating of a dry lubricant, such as molybdenum disulfide or graphite, as a dry powder or as a dispersion in a fluid vehicle.
