Abstract: A fabric coated or impregnated with an elastomeric material may include a polyurethane dispersion layer combined with a sealant. The fabric may be applied in such a fashion so as to enable the elimination of solvent or fluid that is associated with the elastomer. The polyurethane dispersion layer generally comprises an elastomeric material dispersed or dissolved in a liquid medium, such as, but not limited to, water. At the same time, the integrity of the elastomeric composite which is formed from the dispersion and sealant layers may be maintained in order to minimize the presence of air voids and pockets. It has thus been realized that in doing so the performance of the self-sealing volume is dramatically improved. This method of construction usually may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume.
