Abstract:
A chromium-and-ferricyanide-free aqueous cleaner/deoxidizer for aluminum, the cleaner/deoxidizer having an etch rate on titanium that is low enough for practical use in processes where aluminum objects to be deoxidized are held on titanium racks or hangers during the process, combines boric acid, fluoborate anions, and an acid that is stronger than either of boric and fluoboric acids, usually also with an oxidizing agent such as hydrogen peroxide. Rates of etching of aluminum that are at least as much as 50 times the rates of etching of titanium under the same conditions can be achieved, and the deoxidizing of the aluminum is satisfactory for achieving corrosion resistance after subsequent conversion coating of the deoxidized aluminum surface.

Abstract:
Self-dispersing curable epoxy resin ester dispersions prepared by a process comprising reacting a self-dispersing curable epoxy resin based on a polyoxyalkyleneamine with a fatty acid selected from the group consisting of drying oil and semi-drying oil fatty acids, are provided. The sel-dispersing curable epoxy resin is based on a polyoxyalkyleneamine. Thus, a polyoxyalkyleneamine was present as a chemical precursor of the epoxy resin or a starting material therefor. The self-dispersing curable epoxy resin ester of the invention is in the form of an aqueous dispersion. When dried, films of the self-dispersing curable epoxy resin ester dispersion are useful as a coating composition.
Abstract:
An antistatic composition containing (a) a cross-linked thermosetting resin formed by reacting, in the presence of a water-soluble solvent, a polyaminoamide having unreacted primary and secondary amine groups and an anhydride selected from the group consisting of dianhydride, maleic anhydride, and mixtures thereof, and (b) a cationic polymer.
Abstract:
The invention is a cleaning solution for degreasing metal articles which contain water soluble, N-alkyl substituted amides in which the alkyl substituent has from 6 to 22 carbon atoms and at least one of (i) amine oxide surfactants, (ii) non-ionic water soluble surfactants with molecules containing a polyoxyalkylene block, and (iii) alkali stable anionic, or both anionic and amphoteric, surfactants. Preferred compositions of the invention can replace a vapor degreasing process for cleaning oil, grease, and waxy-type contaminants from metal articles to the level of cleanliness required in the aerospace industry.
Abstract:
The removal of dried paint residues from difficultly accessible surfaces is substantially speeded up by using particulate solids, which are insoluble in conventional liquid solvent-swellant compositions for removing paint residues but are soluble in water, in the form of a slurry of the particulate solids in a conventional liquid cleaner composition for paint residues, contacting the paint residues with the slurry while it is maintained in turbulent motion, removing the slurry, and rinsing with water, so as to dissolve any remaining solids from the slurry that might later contaminate the cleaned surface.
