The purpose of this presentation is to clearly show the use of one component uv-cured epoxy resin coating formulation as a new coating repair service system for coated tanks and other ships. The developed repair procedure with the uv-curing of MarineLine® should be used when the protective coating has been misapplied, damaged, or contains holidays or pinholes. Thereto here we report that the developed photopolymerization technology of one component epoxy resin to be used as very efficient replacement of two-component MarineLine® epoxy resin to receive protective coatings for applications and maritime industries where thermal curing processes and two-component resin hardening are unacceptable.
