  • In situ polymeric membrane for isolating hazardous materials
    Patent number: 4632847
    Abstract: A method and composition for providing, in situ, a polymeric membrane for isolating hazardous materials within an area such as, for example, an asbestos removal job site. The polymer is applied in liquid form to surfaces which are to be protected. Upon cure, a seamless bladder-like membrane is formed which isolates the work area and prevents the spread of airborne, or water-carried particulate. The membrane can then be peeled from the surface and compacted for disposal.
