Latest Patents

One of Tokumitsu's latest patents is for a contamination-resistant float glass. This invention provides a glass that maintains even quality in durability while ensuring high standards of cleanliness. The contamination-resistant film is applied solely to the top-side surface of the float glass, which can be identified by ultraviolet irradiation due to the absence of tin diffused from a float bath. A solution containing a chemical adsorbent, such as fluoroalkyltrichlorosilane, is applied using a roller coater. This method prevents hydrolysis of the adsorbent with dry air around the coating area. Surplus solution is removed with dry air, enhancing both the contamination-resistant properties and the appearance of the glass. The chemical adsorbent forms a thin film bonded to the surface via a siloxane bond. This innovative glass is particularly useful when installed in the front door of cooking appliances, such as toaster ovens, with the film facing the interior. In durability tests, the top-side surface exhibits higher contact angles compared to the bottom-side surface.
