Abstract:
1. A chromium-free process for inhibiting corrosion of substrates comprising steel, the process comprising the steps of: a) contacting a clean, untreated surface comprising steel with a corrosion inhibitor composition for 0.5 to 60 seconds at a treatment temperature of 10° C. to 50° C., said corrosion inhibitor comprising: b) removing excess corrosion inhibitor, if any, from the substrate; and c) applying a suitable supply of energy for 0.1 to 120 seconds to the corrosion inhibitor to polymerize the monomers and form a polymeric film on the substrate, said polymeric film having a weight per unit area of 0.1 to 10 g/m
