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 cooperate, 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.

Structure protectrice pouvant servir de revêtement protecteur contre les fuites de carburant sur la surface extérieure d'un contenant de liquide. Ce revêtement comprend une première couche composée d'un élastomère possédant une capacité d'étirement élevée qui peut également absorber les fuites de liquide du contenant et gonfler pendant ce processus, et une seconde couche adjacente à l'un des côtés de la première couche, de nature composite et contenant des granulés occlus dans le même élastomère que celui de la première couche. Ces éléments occlus sont également conçus pour absorber les fuites de liquide du contenant et gonfler au moment de l'absorption. Ce brevet a également trait à la méthode qui consiste à appliquer sur la surface extérieure du contenant un revêtement possédant des caractéristiques de pénétration et de scellage, comprenant a) une élasticité avant rupture d'environ 300 % à 400 %, b) le gonflement au contact de la fuite de liquide et la coagulation provoquée par le contact du liquide et du revêtement.
