In-situ polymeric membrane for cavity sealing and mitigating transport of liquid hazardous materials based on aqueous epoxy-rubber alloys

Abstract

A method and composition for providing a polymeric membrane in situ for isolating vessels which hold hazardous liquid materials. A liquid polymer composition is applied to at least one of the surfaces defining the area which is to hold the liquid hazardous material. Upon cure, a seamless bladder-like membrane is formed which adheres to the surface, and which can be removed by physically peeling from the surface to which it has been applied. The membrane possesses a unique combination of properties which are substantially maintained while in contact with the hazardous material. The polymeric membrane provides, for an extended period of time, an impermeable barrier which acts as a secondary sealant and prevents the spread, deposition, or migration of contaminants.
