For Removing Asphalt, Tar, Or Hardened Cementitious Material (e.g., Concrete, Etc.) Patents (Class 510/366)
  • Patent number: 10577563
    Abstract: Certain fatty acid amide-based surfactants such as cocamide DEA (also known as “coco(nut) diethanolamide” or “coco(nut) DEA”) when dissolved or dispersed in a cutting oil (diesel, light cycle oil, naphtha, and such other petroleum distillates) produce a petroleum distillate having significantly enhanced solvency for heavy residuals. Such solutions or dispersions are especially useful for cleaning vessels and similar equipment in refineries by circulating the solution or dispersion in the vessel, optionally with the application of heat.

  • Patent number: 6126757
    Abstract: A method of preventing asphalt and tar from sticking to paving equipment comprises diluting a concentrate with about four to about 50 parts water to one part concentrate and spraying, rolling or brushing the diluted concentrate on the equipment, coating the dilution on equipment prior to its coming into contact with tar or asphalt. The concentrate comprises a fatty acid amide or mixture of fatty acid amides, a fatty acid neutralized with an excess of an alkyl- or alkanol- or mixed-type amine or ammonia, and an optional solvent or solvents. The chief advantages of the instant invention are that the dilutions are viscous, and so prevent the diluted material from running off of the equipment prior to contact with tar or asphalt, and that the diluted material leaves a lubricious film on the surface even after all the water in the diluted film has evaporated.

  • Patent number: 5929005
    Abstract: This invention provides graffiti removers for removing permanent ink stains from painted surfaces. The graffiti removers include an active solvent for dissolving the stains, which are organic in nature, an optional secondary solvent for concentrated attack on the stain without being adversely affected by dilution with water, an emollient for maintaining a uniform dispersion of particulates in the remover and on the graffiti-stained painted surfaces, and an amorphous, particulate, mildly abrasive filler for imbibing the solvents, the filler being selected to permit the slow release of the active solvent.

  • Patent number: 5888279
    Abstract: An asphalt release agent for preventing hot road asphalt, especially polymer-modified asphalt, from sticking to surfaces of delivery truck beds is provided. The release agent includes a water-based mixture of polycycloaliphatic amines and polyalkylene glycols. The release agent is applied onto the truck beds to create a slippery non-stick surface so that the road asphalt which comes in contact with such truck bed surfaces will not adhere.

  • Patent number: 5549839
    Abstract: An industrial solvent that is non-toxic, biodegradable, and completely safe for human and animal contact, based primarily on a d-limonene composition made up of 95 percent pure d-limonene in approximately 73 to 74 percent volume, a surfactant such as ethoxylated nonyl phenol in approximately 16 to 17 percent by volume, and a tall oil fatty acid in approximately 9 to 10 percent by volume, which is mixed together in a liquid form and applied directly at full strength to an oil spill or other waste petroleum products such as tar or grease, the composition being completely safe and cost effective for petroleum waste cleanup.

  • Patent number: RE41938
    Abstract: Methods, compositions and kits for masking and subsequent removal of oil, grease, rust and other stains from a variety of rough solid surfaces, including, but not limited to stone, concrete, asphalt, stucco brick, and ceramic. The methods include coating the stains with an opaque or translucent thin film of a composition that makes the stain practically indistinguishable against the background, exposing the coated stain to the elements, such as, sunlight, air, moisture, resulting in spontaneous transformation, degradation and subsequent removal of the stains from the solid surfaces. The compositions include a photocatalyst by itself or the photocatalyst combined with at least one of, a sensitizer, a dopant, a mediator, a co-reagent, a pigment and a binder. The role of a photocatalyst is to produce highly reactive species or radicals and initiate the degradation of a stain upon exposure to elements, such as, sunlight, air and ambient humidity. Artificial light sources can be used instead of sunlight.
