Upon application of the composition to a polyurethane adhesive/sealant, the adhesive bond of the polyurethane is destroyed allowing for ease of removal without affecting materials previously bonded.Type: GrantFiled: October 31, 1997Date of Patent: January 5, 1999Assignee: Nouveau Technologies, Inc.Inventors: Jack G. Wiersma, Theodore G. Christian

Patent number: 5759975Abstract: A cleaning composition for paint delivery systems includes 3-90% of an organic solvent which may comprise one or more aromatic hydrocarbons, aliphatic hydrocarbons and aliphatic esters. The composition also includes between 0.5 and 30% of a hydroxy carboxylic acid such as glycolic acid, as well as a coupling agent which may comprise one or more alcohols, glycols or glycol ethers.Type: GrantFiled: August 26, 1996Date of Patent: June 2, 1998Assignee: Gage Products CompanyInventor: Jeffrey W. Maxwell

Patent number: 5744438Abstract: Stripping action of an alkaline paint stripper is improved when ammonia is partially or completely replaced with ammonium bicarbonate or chemical equivalent thereof which decomposes into ammonia and carbon dioxide. A benzyl alcohol solvent system containing at least ammonium bicarbonate is preferably a water-in-oil emulsion emulsified with oleic hydroxyethyl imidazoline and thickened with hydroxypropyl cellulose or hydroxypropyl methylcellulose. A mixture of ammonium carbamate and ammonium bicarbonate identified as ammonium carbonate is the preferred activator for this alkaline paint stripper. Improved stripping can also be provided by reacting ammonium bicarbonate and ammonia in situ within the water-in-oil emulsion.Type: GrantFiled: July 26, 1996Date of Patent: April 28, 1998Assignee: Elf Atochem North America, Inc.Inventor: John Distaso

Patent number: 5665690Abstract: A low-toxicity solvent composition having broad-spectrum applicability. A polar solvent component is provided by an alicyclic carbonate and a non-polar solvent component is provided by a terpene, with a short-chained non-ionic surfactant being provided for coupling the alicyclic carbonate and terpene in a homogeneous, single-phase solution. The composition may be 25-60% propylene carbonate, 1% (or less)-20% d-limonene, and 40-60% tripropylene glycol methyl ether. This solvent composition is non-toxic to personnel, and presents minimal environment hazards. Among its many applications are paint equipment clean-up, cleaning and reclamation of silkscreens, cleaning of offset printing rollers, cleaning of aluma-printing surfaces and equipment, as well as general purpose clean-up of greases, oils, paints, inks, and so forth.Type: GrantFiled: August 30, 1995Date of Patent: September 9, 1997Assignee: Inland Technology IncorporatedInventors: Joseph A. Lucas, Zeljko E. Halar

Patent number: 5609678Abstract: Solvent formulations used in thinning oil-based resins and in cleaning equipment contaminated with oil-based resins include mixtures of constituents with low-, or no-toxicity and flash points generally considered to be above flammability levels. The formulations are compatible with such resins and further have drying characteristics suitable for most users. The solvating power and drying characteristics of these formulations are equivalent to turpentine and mineral spirits, but without the safety concerns associated with those thinners. The formulation components of the present invention include propylene glycol ethers comprising no more than 60% by weight of the solvent mixture, no more than 10% by weight of an isoalkane compound, and no more than 30% by weight of an oxidizing oil, and no more than 30% by weight of an odor-masking compound, preferably d-limonene.Type: GrantFiled: May 9, 1995Date of Patent: March 11, 1997Assignee: American Color CompanyInventor: Leo M.
