Corrosion is an expensive issue for the Navy. Epoxy based protective coatings are used by the Navy to minimize corrosion. The goal of this work is to reduce the cost of corrosion by improving the reliability of the coating application. A better application process decreases defects and reduces early failures. A novel hybrid epoxy coating system composed of two layers has been developed. A first layer with two curing stages (an epoxy/amine polycondensation combined with a vinyl free radical polymerization) and a standard second layer were created and tested. A room temperature free radical initiator system was selected to perform the free radical polymerization. Diffusion predictions were carried out in order to determine the viability of the initiator diffusion. Kinetics measurements and theoretical modeling were performed in order to characterize the curing behavior. A novel formulation was developed and showed a potential for practical application.
