Abstract: An improved paint stripper is provided and comprises at least one paint-stripping agent modified with at least one heavy metal remediation agent. Optionally, one or more viscosity-modification agents, dispersants, or other additive is also included. The invention also provides a kit for making a heavy metal-remediating paint stripper, comprising a vessel containing a paint-stripping agent and a dissolvable packet containing a remediation agent. To use the kit, a painter or other laborer opens the vessel containing the paint-stripping agent and deposits therein the packet containing the remediation agent. The packet dissolves, thereby releasing the remediation agent into the stripping agent.

Abstract: A composition for stripping and cleaning organic coatings from substrates, comprising a solution of high-boiling alcohols, preferably polyglycols, a surfactant, preferably a nonylphenol ethoxylate, and an alkali metal hydroxide, said composition being essentially free of any amines. The composition aggressively and effectively strips paints and other organic coatings without harming underlying substrates damaged by prior art strippers, over conventional or lower time periods, and at conventional or lower temperatures. One embodiment of the invention comprises from about 40% to about 98.9% by weight of a high-boiling alcohol; from about 1% to about 60% of a non-ionic surfactant; and from about 0.1% to about 10% of an alkali hydroxide or mixture of alkali hydroxide.

Abstract: The invention provides a method for the removal of contaminating materials from pipework, the contaminating materials comprising deposits on the pipework which cause a reduction in the effective internal diameter of the pipes and thereby effect a reduction in the rate of flow of a fluid through the pipework, the method comprising treating the contaminating materials with at least one carbamate salt. The methods is also suitable for the treatment of contaminating materials which have a particularly deleterious effect on fluid flow and comprise partial or total blockages of the pipework. The carbamate is preferably in the form of an aqueous solution, and a preferred carbamate salt is ammonium carbamate. The treatment may be carried out in the presence of an additive such as caesium carbonate or ammonium bicarbonate. Optionally the treatment may be accompanied by a pre-treatment or post-treatment with aid, this being followed by a water wash.

Abstract: A process for making a chemical composition includes the steps of mixing 200–800 parts by volume of petroleum solvent with 10–500 parts by volume of normal paraffin or isoparaffin at room temperature to form a solvent paraffin mixture. A microcrystalline wax is heated to between 180–200 degrees Fahrenheit until melted and 90–700 parts by volume of melted microcrystalline wax is vigorously mixed with the normal paraffin or isoparaffin mixture to form a creamy liquid useful as a hand cleaner and paint remover as well as a fire starter.

Abstract: The present invention relates to a water-soluble composition for removing rust from steel bars and steel frames, which is environmentally harmless and permits improving work efficiency by allowing work to be conducted in a state where rust was simply removed from the steel bars and frames by applying it on the steel bars or frames with a spray or brush. The rust-removing preparation of the present invention comprises a mixture of 10-11% by weight of phosphoric acid, 6-7% by weight of sodium pyrophosphate, 6-7% by weight of a hard water softener, 7-8% by weight of zeolite, 2-3% by weight of xanthan, 2-3% by weight of a surfactant, 4-5% by weight of stearic acid, 6-7% by weight of methyl alcohol and 2-3% by weight of a defoamer in 50-51% by weight of water.

Abstract: A pleasant smelling, non-toxic dry composition comprised of sodium bicarbonate embedded in a rubber matrix for removing adhesives from smooth surfaces is described. The composition is prepared by mixing 2 volumes of packed sodium bicarbonate with one volume of rubber cement and allowing the mixture to dry. The dry composition is dispensed from a tube type dispenser. The adhesive is removed by rubbing the dry composition against the adhesive until the smooth surface is clean.

Abstract: 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.
