Abstract:
A process is provided for applying printed matter to plastic substrates by coating the substrate with a composition capable of generating aluminum phosphate. A complex aluminum phosphate having at least 1 chemically-bound molecule of an hydroxy compound ROH where R is hydrogen or an organic group is preferred. The coating is heated to provide at least a partially cured layer of aluminum phosphate and the inked pattern is applied thereto.
Abstract:
A method of coating a substrate with aluminum phosphate comprising coating the substrate with a composition capable of generating aluminum phosphate on drying and heating the application and drying of the coating composition being effected under conditions such that the surface tension of the coating composition is not allowed to exceed the critical wetting tension of the substrate.
Abstract:
Glass laminates comprising two sheets of glass bonded together by a transparent plastics material have at least one of the bonded surfaces of the glass provided with a layer of aluminum phosphate. The aluminum phosphate is preferably generated from an alcoholic coating solution of a complex phosphate of aluminum, e.g., aluminum chlorophosphate ethanolate, which may be applied to the glass surface and cured by gentle heating.
Abstract:
Pre-treatment of a metal, especially aluminum or zinc, prior to painting, by means of a complex halogen-containing phosphorus or aluminum containing chemically-bound molecules of water and/or an organic hydroxy compound. The preferred complex phosphate contains ethyl alcohol molecules and has an empirical formula of A1PC1H25C8O8, and is most conveniently used in solution in methyl alcohol or ethyl alcohol.
Abstract:
COMPOSITIONS COMPRISING COMPLEX PHOSPHATES OF ALUMINUM CONTAINING A HALOGEN AND CHEMICALLY-BOUND MOLECLES OF A HYDROXY COMPOUND, WHICH MAY BE WATER OR AN ORGANIC HYDROXY COMPOUND, CERTAIN ORGANIC POLYMERS AND A SOLVENT SYSTEM. A TYPICAL COMPOSITION COMPRISES ALUMINUM CHLOROPHOSPHATE ETHANOLATE AND POLYVINYL BUTYRAL DISSOLVED IN A MIXTURE OF METHANOL AND CHLOROFORM. THE COMPOSITIONS ARE ESPECIALLY USEFUL AS COATINGS FOR SUBSTRATES AS THEY DECOMPOSE ON HEATING AT LOW TEMPERATURES TO FORM FILMS OF ALUMINUM PHOSPHATE AND AN ORGANIC POLYMER.
Abstract:
A composition suitable for a wide range of purposes such as producing shaped articles, including refractory crucibles, which comprises A. A GRAPHITE B. A BINDER CONSISTING OF EITHER I. A COMPLEX PHOSPHATE OF ALUMINIUM CONTAINING AT LEAST ONE CHEMICALLY BOUND MOLECULE OF A HYDROXY COMPOUND, ROH, wherein R is an organic group or hydrogen and an anionic group of a strong inorganic acid, other than an oxy-phosphorus acid, or of a carboxylic acid, or II. AN ALUMINIUM PHOSPHATE IN WHICH THE RATIO OF THE NUMBER OF GRAM ATOMS OF ALUMINIUM TO THE NUMBER OF GRAM ATOMS OF PHOSPHORUS IS AT LEAST 1:1; AND C. A DISPERSANT FOR THE BINDER.
Abstract:
Treating a cellulosic substrate, e.g., paper, wood or cork, by impregnating the surface with a complex phosphate of aluminium containing halogen and chemically bound molecules of a hydroxy compound which may be water or an organic hydroxy compound, and curing the complex, preferably by gentle heating. The complex is most conveniently used in solution in water or an organic solvent e.g., methanol, and the solution may contain further materials, e.g., an organic polymer. Products are more durable and less permeable than the original cellulosic materials.
Abstract:
Complex halogen-containing aluminum phosphates are prepared by contacting aluminum orthophosphate hydrate with hydrogen chloride, bromide or iodide. The complexes produced are useful as refractory binders.
Abstract:
INORGANIC FIBROUS MATERIALS ARE BOUND TOGETHER IN FELTED FORM BY TREATMENT WITH A SOLUTION OF EITHER (I) A COMPLEX PHOSPHATE OF ALUMINUM CONTAINING AT LEAST ONE CHEMICALLY-BOUND MOLECULE OF A HYDROXY COMPOUND, ROH, WHEREIN R IS AN ORGANIC GROUP OR HYDROGEN AND AN ANIONIC GROUP OF A STRONG INORGANIIC ACID, OTHER THAN AN OXYPHOSPHORUS ACID, OR OF A CARBOXYLIC ACID, OR (II) AN ALUMINUM PHOSPHATE IN WHICH THE RATIO OF THE NUMBER OF GRAM ATOMS OF ALUMINUM TO THE NUMBER OF GRAM ATOMS OF PHOSPHORUS IS AT LEAST 1:1, AND THEN HEATING AN ENTANGLES MASS OF THE FIBERS SO AS TO DEPOSIT ALUMINUM PHOSPHATE FROM THE SOLUTION.
