  • Patent number: 8957007
    Abstract: A metal-safe dissolving composition for cured resins, comprising a solvent blend that includes a metal safe solvent mixture with addition of a soluble alkali that exhibits a pKa value ?12. The solvent mixture may include the preferred solvent for metal safety, gamma-butyrolactone (GBL), and the preferred soluble amine, 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU). The solvent, n,n-dimethylacetamide (DMAC) or others, are chosen for high penetration and solvency to polar resins. To this mixture, a surfactant, inhibitor, and cellulose derivative may be added to produce a gel-form property. The product may be used to remove coatings and sealants present on vertical and horizontal surfaces and hard to reach areas commonly encountered when performing maintenance on aviation fuel tanks and similar equipment. Of key importance for the remover is its safety to aluminum and aluminum alloy substrates as demonstrated by modified test methods for sandwich corrosion, for example, ASTM F1110.

  • Patent number: 8025741
    Abstract: Coatings are stripped from substrates by means of a stripping composition which comprises at least one low vapor pressure solvent. The stripping compound is applied to a coated surface of the substrate and is allowed to dwell in contact with the coating. The coating and stripping compound are removed, separately or together, and the stripping compound is reused to strip the same or a different substrate.

  • Patent number: 8007687
    Abstract: An organic solvent which is very useful in paints is made up primarily of n-butyl acetate, n-heptane, methyl ethyl ketone, methyl isobutyl ketone, acetone and a light hydrotreated petroleum distillate. The solvent typically has a closed cup flash point of about 50 to 75° F. The petroleum distillate typically has a boiling range from 230 to 320° F., a closed cup flash point from 35 to 75° F. and a kauri-butanol value not less than 25. A mixture of 8-carbon and 9-carbon hydrocarbons which are typically primarily paraffins or cycloparaffins typically makes up the vast majority of the petroleum distillate.

  • Patent number: 7977294
    Abstract: The present invention includes a process using environmentally friendly materials for the removal of adhesive residues from hard substrates, particularly vehicles, e.g., cars, trucks, buses, aerospace vehicles including airplanes, and the like. The process uses a novel adhesive remover composition comprising one or more non-halogenated organic solvents, a non-abrasive thickening agent, a surfactant, and a vapor-pressure modulating agent. The total Hansen Solubility Parameter (?t) at 25° C. for each of the non-halogenated organic solvents is from about 14 MPa1/2 to about 24 MPa1/2. The invention provides a cost effective, safe, environmentally friendly adhesive remover composition specifically formulated for removal of, e.g., pressure sensitive adhesive residues from large areas of aircraft composite and aluminum surfaces, as well as others.
