Patent number: 7204890Abstract: Many prior art processes for cleaning predominantly organic hard surfaces have been found to be considerably less effective in removing very fine particles on such surfaces than are the best cleaners for metallic surfaces. However, it has been found, and forms the basis of this invention, that fine particles can be removed effectively from organic surfaces by an indirect process of first forming a thin solid coating over the surface and then removing the solid coating, into which the fine particles that formerly contaminated the surface to be cleaned have presumably become incorporated. Substantially hydrolyzed poly(vinyl acetate) has been found particularly useful for forming the thin solid coating when this coating is to be removed by treatment with an acidic aqueous solution; acrylate polymers are preferred if the solid coating is to be removed by an alkaline aqueous solution.Type: GrantFiled: January 19, 2001Date of Patent: April 17, 2007Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Theodore D. Held, III, Gerald J. Cormier, William E. Fristad

Patent number: 6495084Abstract: Dispersions of waxes in water are now widely used as molding aids, mold release agents, and the like but often leave troublesome residues that can not be easily washed away with water. This problem can be avoided by use instead of a solution in water of certain organic materials, preferably a combination of glycerine and an alkyl imidazoline surfactant.Type: GrantFiled: May 10, 2000Date of Patent: December 17, 2002Assignee: Henkel CorporationInventors: Theodore D Held, III, Douglas J Lasky

Patent number: 6005668Abstract: A "highlighter" liquid for detecting cosmetic defects in non-metallic surfaces, particularly those intended for high quality automotive finishes comprises organic substances each molecule of which contains at least one continuosly chemically bonded chain or ring of atoms in which there are at least two carbon atoms and at least two oxygen, nitrogen, sulfur, and phosphorus heteroatoms, the carbon atoms and heteroatoms being arranged in such an order along the chain or ring that (i) each heteroatom is bonded to at least one carbon atom and (ii) the chain does not include more than three consecutive continuosly chemically bonded carbon atoms. Particularly suitable materials include glycerin, propylene glycol, low molecular weight glycol condensation polymers, and monoethers of these glycol condensation polymers.
