  • 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: 7767637
    Abstract: A solvent for urethane adhesives and coatings, the solvent having a carbaldehyde and a cyclic amide as constituents. In some embodiments the solvent consists only of miscible constituents. In some embodiments the carbaldehyde is benzaldehyde and in some embodiments the cyclic amide is N-methylpyrrolidone (M-pyrole). An extender may be added to the solvent. In some embodiments the extender is miscible with the other ingredients, and in some embodiments the extender is non-aqueous. For example, the extender may include isopropanol, ethanol, tetrahydro furfuryl alcohol, benzyl alcohol, Gamma-butyrolactone or a caprolactone. In some embodiments a carbaldehyde and a cyclic amide are heated and used to separate a urethane bonded to a component.

  • Patent number: 7759298
    Abstract: The present invention includes a process using environmentally benign 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 invention uses an absorbable indicator (tracer) dye to aid in detection of remaining residues that may be in need of additional cleaning. The process uses a novel adhesive remover composition comprising a non-halogenated organic solvent, a non-abrasive thickening agent, a surfactant, glycerine, and an absorbable indicator dye. 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.
