  • Publication number: 20100273696
    Abstract: An environmentally safe formulation to prepare an effective and permanent protection layer on almost all surfaces. The formulation consists of a combination of different silicon organic compounds, namely [a] end standing mono-, di- or tris-amino-alkyl-alkoxysilanes and [b] mono-, di-, or tris-alkyl-amino-alkylsilanes, in a long-chained isoparaffinic solution. The silicon organic compounds starts to polymerize in the presence of oxygen (air) and/or water (humidity), and builds up a net structure that water molecules can penetrate through the cured protective layer. Depending on the types of the silicon organic compounds, the pore width of the net structure can be verified. It is also possible to remove this protection layer, by using a special water based mixture of hydrofluoric acid and an inert surfactant.

    Abstract: The present invention is a cleaning composition for use with firearms and industrial items in which all of the components of the composition are biodegradable. The selected components of the composition also have a combined flashpoint of over 200° F. The low volatility of the composition enhances the safety factor by its reduced flammability in conjunction with the low odor and other benefits obtained by the biodegradability of the composition. The composition essentially comprises a hydrocarbon solvent and a lubricant which effectively removes the fouling present within the interior arm of a firearm bore and at the same time lubricates and protects the firearm bore to help prevent the formation of rust.

  • Patent number: 7468345
    Abstract: A concentrated non-aqueous cleaning solution having a long shelf life includes an ester and an anhydrous surfactant. The ester is the active ingredient for dissolving graffiti, grease and other contaminants. The ester can be one of or a mixture of dimethyl glutarate, dimethyl succinate, dimethyl adipate, ethyl lactate, and a methyl ester extracted from soybean oil. The anhydrous surfactant is preferably alcohol ethoxylate. The ester in the concentrated solution does not degrade into an acid and alcohol as long as the solution is not mixed with water. This allows the concentrated solution to be shipped and stored and remain efficacious. The concentrate can be diluted with water immediately prior to use. Diluting before use makes the graffiti cleaner less expensive and prevents damage to sensitive surfaces but does not provide long enough time for the ester to degrade.

  • Patent number: 7365046
    Abstract: A method for stripping a floor using a concentrate prepared by mixing a substantially nonchlorinated concentrate containing a floor finish solvent and an at least partially unactivated water thickener. The concentrate is diluted merely with water at an intended use location to activate the water thickener and noticeably increase within ten minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.

  • Patent number: 7304021
    Abstract: A color change paint and varnish removal formulation is provided. The formulation comprises: at least one penetrant, at least one carrier and at least one colorant whereby the formulation is applied to the target area and as the surface of the formulation dries, the carrier partially dehydrates emitting white light as the colorant migrates away from the dehydrating surface and there is a color change to indicate that the stripping action of the formulation has ceased and is ready for the scraping and removal step.

  • Patent number: 7258750
    Abstract: A process for removing paint from a plastic substrate that typically includes immersing and optionally agitating the painted plastic substrate in a first chemical fluid, removing the substrate from the first chemical fluid, typically immersing and optionally agitating the substrate in a second chemical fluid, removing the substrate from the second chemical fluid, optionally immersing and optionally agitating the substrate in a third chemical fluid, where the third chemical fluid typically includes substantially the same chemicals as the second chemical fluid, rinsing the substrate, and drying the substrate. The present invention also includes a method for recycling an initially painted plastic substrate.

  • Patent number: 7229953
    Abstract: A process of stripping a coating according to the invention comprises subjecting a coated substrate to an aqueous medium containing a peroxide and an interfacial mixing agent, and to heating preferably by either ultraviolet (UV) and/or infrared (IR) radiation. The substrate is completely stripped of the coating and suffers no damage to itself as a result of the paint debonding/dislodging process. No toxic wastes are generated from this process, nor are particulates associated with air pollution generated. The metal substrates being stripped also do not undergo corrosion or other damage as a result of the described process.

  • Patent number: 7208457
    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.
