Abstract:
An aqueous alkaline degreaser for aluminum and its alloys that continues to function effectively, even after being loaded with soils in an amount up to three times the weight of the active degreasing agents included in it, comprises alkali silicate(s) as builders and amine oxide(s) with one long and two short chains as surfactants.
Abstract:
The present invention is a process for the scission and oxidation of ozonide materials. The process comprises introducing an oxygen-containing gas stream into an agitated liquid body in the form of fine bubbles.
Abstract:
Pharmaceutical compositions comprising natural tocotrienols and natural tocopherols are disclosed. Also disclosed is a method for preventing or treating the harmful effects of high serum cholesterol and/or lipid levels in a mammal, said method comprising orally administering approximately 100 mg to approximately 1000 mg of natural tocotrienols and approximately 100 mg to approximately 1000 mg of tocopherols to a mammal, including humans, in need of such prevention or treatment.
Abstract:
Aqueous lubricant dispersions having a solids content of from about 45 % by weight to about 75 % by weight contain calcium stearate and a lubricant component with or without a dispersing agent or urea for addition to aqueous paper and paperboard coating compositions.
Abstract:
Self-dispersing curable epoxy resin dispersions prepared by a process comprising reducing the particle size of a mixture comprised of a self-dispersing curable epoxy resin based on a polyoxyalkyleneamine, water and an organic cosolvent and removing at least a major amount of said organic cosolvent from said mixture after said reducing, are provided. The self-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 of the invention is in the form of an aqueous dispersion. When cured, films of the self-dispersing curable epoxy resin dispersion are useful as a coating composition.
Abstract:
Provided are epoxy curing agents comprising the reaction product of reactants consisting essentially of a mono-alkylene polyamine having less than about 12 carbon atoms, an alicyclic diamine in an amount of greater than about 10 % of the amine equivalents of said amine component, an aromatic monoglycidyl ether having less than about 18 carbon atoms, and a diglycidyl ether of an aromatic diol having an average degree of oligomerization of less than about 3.5, wherein the ratio of primary amine equivalents of said alkylene polyamine to the total epoxide equivalents of said aromatic glycidyl ether and said diglycidyl ether of an aromatic diol is/are greater than one, and the ratio of epoxide equivalents of said aromatic mono-glycidyl ether to epoxide equivalents of said diglycidyl ether of an aromatic diol is greater than one. The reaction product is preferably employed as a curing agent for an aqueous epoxy resin in a two component coating system wherein said curing agent, essentially free of acids, is mixed with an aqueous epoxy resin emulsion and then the resulting mixture is applied as a continuous coating to a rigid substrate, e.g. as an industrial maintenance coating.
Abstract:
Soiled metal surfaces can be cleaned in a small-scale facility without producing substantial effluent from cleaning by (i) using a water-based cleaner, with or without a subsequent water rinse step, that contains an ultrafilter-permeable corrosion preventive agent, (ii) ultrafiltering the cleaner and/or the rinse water after use, (iii) using the permeate from ultrafiltration as a final rinse of the metal surface to be cleaned, and (iv) returning the effluent from this final rinse and the non-permeating portion of the ultrafiltered cleaner/rinse water to one of the baths used for cleaning and/or for rinsing.
Abstract:
Surfactant mixtures of an alkyl naphthalene sulfonate and an alkyl polyglycoside, wherein the alkyl polyglycoside is present in from 5 to 25 % by weight of the surfactant mixture, and aqueous pesticide compositions containing the surfactant mixture.
Abstract:
An aqueous liquid composition that has a pH from 1 to 4.0 and comprises from 1 to 80 pbw (parts by weight) of phosphate ions, from 1 to 15 pbw stoichiometric equivalent as zirconium atoms from soluble zirconium compounds, from 3 to 100 pbw stoichiometric equivalent as fluorine atoms of soluble fluorides, and from 1 to 100 pbw of oxidant rapidly produces a very corrosion-resistant and highly paint-adherent coating on the surface of aluminiferous metals when contacted with them at 30 DEG C to 50 DEG C for 2 to 30 seconds, followed by a water rinse and drying by heating.
Abstract:
A self-dispersing curable epoxy composition is prepared upon contacting: (a) 1.0 reactive equivalents of an epoxy resin, (b) from about 0.65 to 0.95 reactive equivalents of a polyhydric phenol, and (c) between 0.005 and 0.5 reactive equivalents of an amine-epoxy adduct, wherein the amine-epoxy adduct is formed upon contacting 1.0 equivalents of an aliphatic polyepoxide and between 0.3 and 0.9 reactive equivalents of a polyoxyalkyleneamine. The self-dispersing curable epoxy resin forms an aqueous dispersion upon mixing with water. When cured, the dispersion is useful as a coating composition.
