Abstract
A method of removing a coating material from a substrate surface portion comprises providing a substrate having a coating material adhered to a surface thereof. The coating material comprises a CO2-soluble material. The coating material is contacted to a fluid comprising carbon dioxide to dissolve the coating material therein. The carbon dioxide fluid is then separated from the substrate to remove the coating material from the substrate surface.
Claims7
A method of removing a coating material from a substrate surface portion, said method comprising:
- providing a substrate comprising a component selected from the group consisting of CO2-insoluble polymers, metals, ceramics, glass, and composite mixtures thereof, wherein said substrate has a coating material adhered to a surface thereof, said adhesive coating material consisting essentially of CO2-soluble material comprising a substituent selected from the group consisting of fluorinated components, siloxane-containing components, and mixtures thereof;
- contacting said coating material to a fluid comprising carbon dioxide to dissolve the coating material therein;
- and then
- separating said fluid from the substrate to remove said coating material from the substrate surface.
