The National Shipbuilding Research Program. Development of Non-Polluting, Solvent-Free, Liquid Resin Coating Systems For Ships
Abstract
The objective of this research was to develop liquid, solvent-free coating systems and practical methods for their application in the shipyards. Successful attainment of this objective would result in (1) lower cost due to elimination of solvents, faster application and fewer coats, (2) ecological advantages resulting from elimination of solvents, and (3) improved safety since elimination of solvents will decrease tire and toxicity hazards particularly in confined areas such as ship holds and tanks. The completed research has demonstrated the feasibility of solvent-free liquid resin coatings under laboratory conditions. Several combinations of pigmented epoxy resin and pigmented polyamide resin were successfully applied to test panels using commercially available, two-component, high pressure air less spray equipment. Two pigmented polyurethane coatings were also applied successfully, one formulated for tank use and the other tor topsides. It is recommended that the coatings developed as a result of this research program be evaluated for long-term durability and ease of application in a shipyard environment as a continuation of this effort. If such evaluation proves successful, the coatings should be applied to a ship for in-service evaluation.
