Patent ID: 8389063

Claim:
A method for spray-creating a liquid fuel reactive composite-material layer useable in a self-sealing coating applied to the outside surface of a target liquid container for defeating a puncture-produced leakage wound in that container utilizing an air-formed, pre-impingement blend of a first, initially wet, but subsequently curable-to-dry, liquid fuel reactive, high-elastomeric body-forming material, and a second, dry, liquid fuel reactive, liquid-imbibing, bead-element, material, said method comprising creating differentiated, simultaneous sprays of desire-relative-percentage amounts of these two materials, using a first spray head for spraying the first material and a second spray head for spraying the second material, and performing said creating so that, during materials spraying, the two materials become contact-blended in air into a composite spray en route toward a target liquid container, with the sprays, in the air, becoming fully overlapped and merged as a completed, combined, composite-material blend by the time that the merged and combined sprays reach and effectively impinge the target liquid container, and as a part of said creating, controlling the amount of en route, inter-material, pre-impingement, contact blend time between the two materials via positioning the spray heads relative to one another and relative to the outside surface of the liquid container, and by said positioning, adjusting the length of time in air that the second, bead-element material is in contact with the first material so as ultimately to control the liquid fuel reactive characteristics of the intended, composite-material layer.
