Abstract: A solvent mixture comprising an alcohol, an aromatic hydrocarbon or an organic compound containing carboxyl but not hydroxyl moieties, and optionally and preferably a non-aromatic hydrocarbon or halohydrocarbon is particularly effective in removing incompletely cured residues of a variety of sealing compounds from the surfaces of automobile bodies, without damaging intermediate or final finish coatings for the automobile bodies. The solvent mixture may advantageously be absorbed in a wiping cloth for convenient use.

Abstract: A mixture of two stabilizers, one including benzene rings bearing hydroxyl substituents and the other containing divalent sulfur atoms, is effective in stabilizing tacky polymers that remain solid up to a temperature of at least 160° C. particularly polymers of isobutylene, so that the polymers give long service in the ambient atmosphere as protective layers coated on aluminum substrates and used to line the interiors of paint baking ovens. When accumulated foreign materials accumulate on the coatings, the coating and the accumulated foreign materials can be decomposed to largely volatile products by heating to a temperature substantially higher than the service temperature but not high enough to melt the metal substrate for the coating.

Abstract: A thickened nail polish remover includes a solvent/water blend containing a major amount of organic solvent and a minor amount of water. The nail polish remover also includes a water-wetted thickener that, when dry, is readily dispersible in water but not readily dispersible in the solvent/water blend. The nail polish remover further includes a long chain amine neutralizing agent. The thickened nail polish remover has a viscosity of from 3,000 centipoise to 90,000 centipoise at 21.degree. C. In one embodiment, the thickened nail polish remover is formulated to be easily rinsable from the nails with water, by selecting a long chain amine neutralizing agent so that the neutralized thickener is compatible both with the solvent/water blend and with the water used to rinse the nails. In the method of preparing the thickened nail polish remover, the thickener is prewetted with the water of the solvent/water blend to form a dispersion of the thickener in the water.

Abstract: A process for removing dried paint residues from a difficultly accessible surface is provided. The surface is contacted with a slurry of particulate solids such as sodium hydrogen carbonate in a first liquid such as N-methyl pyrrolidone which is a solvent or swellant for the paint residues, followed by a different liquid such as isopropyl alcohol in which the first liquid is soluble (and which may also optionally contain particulate solids).

Abstract: Residue that accumulates on metallic molding surfaces during repeated molding of plastics such as PVC can be removed by cleaning with an aqueous solution of a glycol or oligo-glycol monoether, an amine, and a chelating agent. The cleaner is sufficiently effective to replace mechanical blasting that was previously required.

Abstract: Described is A method of decreasing the formaldehyde content in an organic paint containing composition comprising the steps of adding to the organic paint containing composition an effective amount of an organic nitrogen containing formaldehyde fixating agent. Suitable nitrogen fixating compositions are nitro parafins, nitro alcohols, amino alcohols, and nitrogen heterocyclic compounds containing from 5 to 8 members in a ring and further containing from 1 to 3 nitrogen atoms per ring and optionally including oxygen atoms present in the ring.

Abstract: Methyl groups on N-methyl aromatic amines are redistributed to ring positions by heating in contact with an aluminum anilide catalyst and a nickel, cobalt, molybdenum or titanium-containing cocatalyst. For example, N-methyl-o-toluidine forms a mixture containing substantial quantities of 2,6-dimethylaniline, 2,4-dimethylaniline, and 2,4,6-trimethylaniline.

Abstract: Methyl groups on o-methyl aromatic amine are redistributed to ortho positions by heating in contact with an aluminum anilide catalyst and a nickel, cobalt, molybdenum or titanium-containing cocatalyst. For example, o-toluidine forms a mixture containing an aniline, o-toluidine, 2,6-dimethylaniline, and 2,4-dimethylaniline.

Abstract: Foamed metal articles having reinforcing fibers, such as inorganic fibers; for example, fiberglass, refractory fibers, and metal fibers, dispersed in the foamed metal for strength improvement. Processes of manufacturing such fiber reinforced foamed metal articles are also disclosed.
