Feasability study of rapid cure coatings for marine environment

Feasibility study on the application of several kinds of rapid cure coating system to water ballast tank was conducted in terms of curing characteristics and coating performance. Coating system employed in this study were three types of solvent free rapid cure epoxy coatings, isocyanate curable polyurethane coating and polyurea coating system. Polyurethane and polyurea coating were especially formulated for sea water ballast tank service. Based on the study of curing characteristics and coating performance of the polyurethane and polyurea coating system, iterms of adhesion, crack resistance, corrosion creep will be discussed in this study.
