Coating procedure for fresh water tanks in large ship using a solvent-free epoxy with 100% Solid Volume Ratio (SVR) has been evaluated. Solvent-free epoxy coatings recommended from five major manu- facturers were evaluated in terms of their sprayability, drying time for recoat, quality of the coated films, and other standard properties as well as the flexibility of the coating materials in terms of the temperature (air and steel). The test results revealed wide differences in the workablity of each solvent-free epoxy materials from different manufacturers, suggesting that data provided by the suppliers were not valid under certain work con- ditions. This study indicated that a certain degree of optimization of "solvent-free" epoxy coating procedure can only be achieved through the user's own evaluation works.
