EFFECTS OF ENERGY, ECONOMICS, AND ECOLOGY ON MARINE COATINGS

Wide-spread and interacting energy, economic, and ecological problems in this country and abroad have spurred investigations into more efficient and ecologically acceptable materials and methods for cleaning and coating ship hulls as well as fixed marine structures. Ecological considerations have restricted methods of cleaning steel for repainting and disposal of waste products from the cleaning operation. The paper reviews current technology regarding organic solvents, alternatives to conventional abrasive blasting, new treatments for fouling, underwater- applicable protective coatings and anti-fouling paints. Two investigations being conducted at the Civil Engineering Laboratory are of special interest because they are directed at saving energy. In one, initial results indicate that roof temperature reductions of 15 to 40 F are possible through use of an efficient heat reflective coating, thus greatly reducing building air conditioning requirements. In another, reflective urethane coatings were applied to the floor of a concrete hangar used for repair of aircraft. This coating significantly reduced lighting requirements especially under wings and other areas shielded from the overhead lighting.
