Efforts have been made to develop a high-quality interior paint for nuclear-powered submarines. Because of the circumstances under which the paint is to be used, it must have properties not previously required for ships in the fleet. It should 1 release little or no toxic or organic material to the atmosphere as it is applied or as it dries, 2 be self-extinguishing in its fire-retardancy performance, 3 have a gloss in the medium range 50 at a 60 degrees angle, 4 be flexible and 5 have a highly decorative appearance in general. Chlorinated compounds and antimony oxide were used to introduce fire retardancy into an acrylic latex paint however, they also affected the physical appearance and performance of the paint. The highest degree of fire retardancy and best over-all properties were obtained when a chlorinated paraffin and antimony oxide were used together. The tentative concentrations have been selected as 34 wt- for chlorine and 14 wt- for antimony oxide, based on the weight of nonvolatile, combustible material in the paint. Further changes are being made in this formulation to improve performance. A film-forming polymer which contains chlorine chemically combined with the polymer was studied, and a formulation was devised making use of this material. It is also undergoing further examination.
