Latest Patents

One of Helman's notable patents is titled "Method for repair of thin glass coatings." This patent describes a method for repairing cracks or damaged areas in glass, particularly glass coatings on tiles. The process involves removing the damaged area using a high-speed diamond burr to drill out a cavity that extends slightly into the base material of the tile. After cleaning the loose material from the cavity, it is filled with a filler material that includes chopped silica fibers mixed with a binder. The filler is packed into the cavity, and a repair coating is applied using a brush or spray. The repair includes borosilicate suspended in solution, and heat is applied at approximately 2100°F for about five minutes to cure the coating. This process causes boron silicide particles to oxidize, forming a highly refractory layer that enhances the glass's integrity.
