Patent number: 6017863Abstract: An alkaline, aqueous cleaning solution which is capable of removing at least a substantial portion of uncured adhesive residues, e.g., epoxy-based adhesives, from a substrate, preferably a metal stencil substrate, contains water, an alkalinity-providing agent and a synergistic combination of surfactants, specifically an N-alkylpyrrolidone surfactant, which is preferably N-octyl-2-pyrrolidone, and an aminocarboxylic acid surfactant, which is preferably N-coco-beta-aminopropionic acid. At an active-concentration ratio of the N-alkyl-2-pyrrolidone surfactant to the aminocarboxylic acid surfactant of from about 1:1 to about 3.5:1 and a total active concentration of at least 0.30% by weight of the aqueous cleaning solution, the N-alkyl-2-pyrrolidone and aminocarboxylic acid surfactants synergistically improve the ability of the solution to remove uncured adhesive residues from the substrate, even at relatively low wash temperatures, e.g., from about 70.degree. F. to less than about 135.degree. F.Type: GrantFiled: May 22, 1998Date of Patent: January 25, 2000Assignee: Church & Dwight Co., Inc.Inventors: Frank Cala, Alfredo Vinci

Patent number: 5994282Abstract: Stripping compositions based on a polar aprotic solvent, an ether and water. The composition is characterized in that it comprises at least the following: 1) a polar aprotic solvent, especially dimethyl sulfoxide (DMSO) or N-methyl pyrrolidinone (NMP); 2) an ether chosen from anisole and tetrahydrofuran (THF); 3) water.Type: GrantFiled: May 30, 1997Date of Patent: November 30, 1999Assignee: Elf Atochem, S.A.Inventor: Jean-Pierre Lallier

Patent number: 5972865Abstract: A purge concentrate for purging paint spraying and other coating equipment has about 20%-60% by weight water; about 10%-40% by weight of an active solvent; about 10%-50% by weight of a co-solvent; about 1-9% by weight of a penetrant; and about 0.2-2.0% by weight wetting agent. It need not be heated to the curing temperature of heat curing paints and thus purges these paints more effectively.Type: GrantFiled: April 30, 1998Date of Patent: October 26, 1999Assignee: Dalco Industries, Ltd.Inventors: Richard E. Knipe, Jr., Savarimuthu M. Jacob, Sheldon Green

Patent number: RE37555Abstract: The invention relates to a method of producing a mixture of a quaternary ammonium compound, fatty acid, fatty acid ester and tertiary amine salt in situ which is a highly functional mixture that is manufactured in a single step reaction whereby quaternization is completed without the aid of solvents, especially flammable solvents. The single step reaction process eliminates separate blending of individual components. The compositions obtained can be used as fabric softeners, in modified clays, as hair treating compounds and as disinfectants.Type: GrantFiled: June 11, 1999Date of Patent: February 19, 2002Assignee: Goldschmidt Chemical CompanyInventors: Jeannene A. Ackerman, Michael Miller, David E. Whittlinger
