Abstract: A thickened binder composition which comprises from about 3 to about 20 weight percent colloidal alumina, from about 1 to about 8 weight percent aluminum chlorhydrate and from about 0.1 to about 0.4 weight percent of an inorganic acid selected from hydrochloric and nitric acids and from about 75 to about 95 weight percent water;the method for manufacturing the binder composition and a fiber article by blending the ingredients of the binder composition with each other and by impregnating or blending fibers with the binder composition to form a fiber containing composition followed by drying and calcining the fiber composition; andan article comprising alumina-containing fibers bound together with alumina.

Abstract: A modified phenol formaldehyde condensate is reacted with boric acid and cured in the presence of a polyfunctional nitrogeneous compound to provide a binder for mineral wool fibers which is particularly suited for thermal insulation products intended for high temperature service.

Abstract: A substrate such as glass contains a coating of a transition metal oxide complex with an ortho functional aromatic compound which contains a functional group which can react with a phenolic or resorcinolic resin or other organic compound or polymer. The ortho functional aromatic compound can also be a phenolic or resorcinolic resin. The complex serves as a coupling agent between the substrate and the organic material. These coupling agents can be resinous coatings or they can be coatings which serve as a coupling agent type of composition for rendering the surfaces of the substrates more substantive or reactive to organic materials. The coatings are inorganic-organic complexes of a transition metal oxide or a hydroxide with an ortho functional aromatic compound. The aromatic compound can contain at least two functional groups in ortho position to each other and a functional group for interfacing or reacting with the organic material.
