Abstract
Cellulose cyanoacrylate is employed to bond two surfaces, fill voids or duplicate the shape of a three-dimensional object, Two surfaces may be bonded by placing a sheet of cellulose material between the surfaces and applying cyanoacrylate glue around the edge of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulose material. A break or fracture in an article can be overlaid with a sheet of cellulose that when saturated with cyanoacrylate glue and temporarily held in place and shaped with a releasable film, the fracture can be corrected. A dry powder comprising highly abrasion-resistant particles can be mixed with the cellulose material to enhance abrasion resistance and to improve long-term color stability—especially important for dental cavity treatment. To duplicate the shape of a three-dimensional object, a sheet of releasable film is placed over the object, followed by a sheet of cellulose that is then saturated with cyanoacrylate glue. A sheet of releasable film is then placed over the cellulose and used to hold the cellulose in place and shape it as it hardens.
