Luminescent and fluorescent additives and sparkle additives may be used in the grout to provide special visual effects in the light or dark.Type: GrantFiled: January 9, 2003Date of Patent: April 19, 2005Assignee: Laticrete International, Inc.Inventor: Rezvan Rooshenas

Patent number: 6833398Abstract: Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. One or more epoxy resins, such as for example, the combination of a diglycidyl ether of bisphenol A and a flexibilizing epoxy resin, may be prereacted to form an adduct of higher average molecular weight than the starting epoxy resins. Said adduct may then be dispersed in water, with the resulting dispersion being used in an autodeposition bath composition.Type: GrantFiled: October 24, 2002Date of Patent: December 21, 2004Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Rajat K. Agarwal, Brian D. Bammel, William E. Fristad, Gregg W. Rossier, Elizabeth J. Siebert, Zhiqi Yang

Patent number: 6685851Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diamines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.Type: GrantFiled: December 21, 2001Date of Patent: February 3, 2004Assignee: PRC-DeSoto International, Inc.Inventors: Randy Edwin Cameron, Frank Rawolle
