ANTI-CORROSIVE WATERBORNE

POLYURETHANE COATING

Generally, anti-corrosive coating is classified according to protective mechanism against corrosion. Our team utilizes conducting polymer-oxide as an advanced anti-corrosion additives in a waterborne polyurethane coating. With the synergistic effect of both barrier protection and passivization of substrate, application of organic-inorganic hybrid nano-composite coatings can significantly increase the corrosion resistance of metallic substrates particularly by shifting the corrosion potential of the metallic substrate to higher values. It can either acts as a physical barrier or as an inhibitory pigments by reduction of corrosion rate. Essentially, this hybrid nano-composite can prevent both undercoating corrosion in saline environment and delamination of the coating. Finally, the ultimate goal of our research team is to develop a novel protective coating blended with organic-inorganic hybrid nano-composite as a corrosion inhibiting pigment applied over ferrous metal in saline environment.
