MAR RESISTANT, CORROSION INHIBITING, WELDABLE COATING CONTAINING IRON POWDER FOR METAL SUBSTRATES

摘要

A weldable heat curable liquid coating composition for steel is provided tha t exhibits improved mar resistance without impairing the weldability characteristics of the coating. To this end, the composition contains a conductive welding aid of iron dust. The weldable coating when applied to steel and cured thereon to a dry film allows for spo t welding of the coated steel without requiring special welding equipment and techniques.
