This report describes work performed to demonstrate the feasibility of using instantly deployable plastic foams to provide flotation for small vessels which are in a sinking condition. The ability to generate foams under fifteen feet of water was demonstrated. These foams provided sixty-one pounds of flotationcubic foot of foam as originally generated. After twenty-four hours immersion under fifteen feet of water, the foams still provided fifty pounds of flotation per cubic foot. Non-burning solventpneumatogen systems were developed for the foams. The use of additives in the foam made it fire retardant. The capability to generate foams down to -10C 14F was demonstrated. Below that temperature, the foam solution becomes too viscous to flow from the storage cylinder. Long-term storage tests are in progress.
