Patent number: 5773403Abstract: A cleaning and drying solvent is disclosed which has excellent cleaning power and drying property and finds uses as a hand-cleaning agent, a precise cleaning agent and a drying agent for industrial parts. Since it does not contain halogens causing the depletion of the ozone layer, it is available as a solvent replacing freon. The cleaning and drying solvent is composed of a siloxane compound, in particular, hexamethyldisiloxane, an azeotropic or azeotrope-like composition of hexamethyldisiloxane and a lower alcohol, or a mixture of hexamethyldisiloxane and each of ketones, carboxylic esters, low molecular saturated hydrocarbons and low molecular alcohols.Type: GrantFiled: July 20, 1995Date of Patent: June 30, 1998Assignee: Olympus Optical Co., Ltd.Inventors: Masamichi Hijino, Michio Shirai, Kunihiko Uzawa

Patent number: 5759618Abstract: A coating composition of an alkoxy silane reacted with the surface of a glass substrate and a cleaning composition and method for cleaning said glass area is disclosed. The coating provides water repellency, durability and ease of cleaning to a glass or other siliceous surface. The coating is formed by applying an excess of an alkoxy solution containing a sulfuric acid to a glass surface with an excess of solution being applied. Preparatory to such coating application, the glass, especially if its surface is a weathered (non-virgin) surface, is cleaned vigorously with a cleaning solution containing water, phosphoric acid, hydrofluoric acid and sulfuric acid.Type: GrantFiled: February 27, 1997Date of Patent: June 2, 1998Assignee: Diamond Seal, Inc.Inventor: George S. Taylor
