  • Patent number: 7229953
    Abstract: A process of stripping a coating according to the invention comprises subjecting a coated substrate to an aqueous medium containing a peroxide and an interfacial mixing agent, and to heating preferably by either ultraviolet (UV) and/or infrared (IR) radiation. The substrate is completely stripped of the coating and suffers no damage to itself as a result of the paint debonding/dislodging process.

  • Patent number: 7001873
    Abstract: A surface which carries a material which is infected with prions is cleaned with an alkaline cleaning solution to remove as much proteinaceous material as possible from the surface. The cleaning agent is an alkaline cleaning agent which attacks prions remaining on the surface and which attacks prions removed from the surface during the cleaning step. After the cleaning solution is drained, a solution of surfactants, buffers, and heavy metal free corrosion inhibitors is circulated over the surface at 50°–60° C. The surfactants disperse and unclump the prion-contaminated material. A strong oxidant, preferably peracetic acid, is added to the solution to bring the peracetic acid concentration to 1,000–2,500 ppm. The peracetic acid or other strong oxidant attacks the prions, particularly the unclumped prion strands, deactivating the prions. After rinsing and drying, the surface may be wrapped in a microbe impermeable barrier and subjected to terminal sterilization, such as steam autoclaving.
