Abstract
Barrier structure placeable as an anti-fuel-leak coating on the outside surface of a liquid container. This coating includes a first-type layer structure formed of a high-elongation-capable elastomer which also is capable of imbibing container leakage liquid, and of swelling in the process, and a second-type layer structure disposed adjacent one side of the first-type layer structure, composite in nature, and possessing bead-like components entrained in the same elastomer employed in first-type layer structure, with these entrained components structured also to be imbibers of leakage container liquid, and to expand on imbibing such liquid. Also disclosed is methodology which involves applying to the outside surface of such a container a coating possessing cooperative, penetration-sealing characteristics including (a) elastic elongatability before breakage within a range of about 300–400%, and (b) leakage-liquid-contact swelling, accompanied by leakage-liquid/coating contact-triggered coagulation.
