Patent number: 7988775Abstract: The present invention provides an aluminum white rust inhibiting composition containing alkali metal metasilicate and alkali metal hydroxide as essential components. The composition described by the present invention can provide an anti-corrosion function to vehicle aluminum parts without a separate surface process, thus reducing the manufacturing cost by reducing the number of processes and improving the durability of the vehicle aluminum parts.Type: GrantFiled: February 10, 2010Date of Patent: August 2, 2011Assignees: Hyundai Motor Company, Kia Motors Corporation, Korea Houghton CorporationInventors: Ji Yong Lee, Dong Ho Kwak, Byung Jun Jung, Sung Hyun Park, Chul Hee Hong, Kwang Soon Kim

Patent number: 6589661Abstract: An aqueous, curable coating composition comprising a mixture of: (a) at least one water-soluble alkali metal silicate and (b) an effective amount of a water-soluble crosslinking agent comprising an alkali metal aluminophosphate, or an alkali metal aluminoborophosphate, or an ammonia aluminophosphate, or an ammonia aluminoborophosphate, or an alkali metal ammonia aluminophosphate, an alkali metal ammonia aluminoborophosphate, or a mixture of two or more of the foregoing phosphates. The coating composition will often not contain any visually discernible precipitate. The coating composition may be applied to a substrate, such as a glass, a ceramic, concrete or a metal and thereafter cured by air drying or by heating to a temperature of up to about 240° C. (or higher, if desired).Type: GrantFiled: November 30, 2001Date of Patent: July 8, 2003Assignee: Neely Industries, Inc.Inventor: James E. Neely, Jr.

Patent number: 5607503Abstract: An insoluble silica based film is formed by placing an ammonium compound and an alcohol as a plasticizing agent in an aqueous solution and blending the aqueous solution with a sodium silicate. The mixture is allowed to condense which produces the insoluble silica-based film. The film is used as a binder, and has particular application as a vehicle in a paint. The invention also describes a method for preparing an insoluble silica-based binder.Type: GrantFiled: September 3, 1993Date of Patent: March 4, 1997Assignee: Refract-A-Gard Pty LimitedInventor: Harley W. Burr
