Temporary Elastomeric Functional Barrier Membrane and Method of Manufacture

摘要

A fluid check valve incorporating a temporary elastomeric functional barrier membrane, the check valve having a sealing member comprising a first elastomer and a barrier membrane comprising a second elastomer, different from the first elastomer, disposed directly upon the surface of the sealing member so as to form a continuous layer over at least a seal opening of the sealing member. The barrier membrane may include a photoinitiator and coagent which aids in the ultraviolet (UV) curing of the second elastomer after application upon the first. The barrier membrane may applied as a solution of monomers, photoinitiator, and optional coagent, the solvent evaporated, and the deposited solutes exposed to ultraviolet so as to form the barrier membrane material.
