Abstract:
A corrosive resistant coating with deep drawability characteristics which is applied to a metal substrate as a wet film and then heated to dry and initiate curing to provide a protective coating tenaciously bonded to the substrate. The composition has a corrosion inhibiting powder metal, a drawing agent of polytetrafluorethylene (PTFE), a primary bonding resin, and a vehicle of solvents. Preferably, the coating composition also has a secondary organic resin and thixotropic, metal suspension and hydroscopic agents. The cured coating composition on a metal substrate, in most instances, eliminates the needs for additional die drawing compounds when deep cold drawing the coated metal substrate.
