Title: Paints or like coating materials and method of manufacturing them
IPC: C09D7/62
Filed: 1934-09-11
Abstract: Paints and like coating-compositions are made by incorporating finely comminuted foliated glass, as a base or filler, in a vehicle which will harden.  The glass may be plain, coloured, opaque or opalescent, and may have heat resisting and insulating properties, and after foliation, as by blowing into bubbles until they break, may be ground to such a fineness that it will pass through a screen of 325 meshes per linear inch.  Specification 345,845 is referred to.  According to the Specification as open to inspection under Sect. 91, the foliated glass may be incorporated with a synthetic resin to produce an insulating compound.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specification 345,845.ALSO:Paints and like coating-compositions are made by incorporating finely comminuted foliated glass, as a base or filler, in a vehicle which will harden. Specified vehicles are linseed oil, tung oil, varnishes and lacquers. The glass may be plain, coloured, opaque or opalescent, and may have heat resisting and insulating properties, and after foliation, as by blowing into bubbles until they break, may be ground to such a fineness that it will pass through a screen of 325 meshes per linear inch.  It may be added alone to the vehicle, may be incorporated with usual pigments such as lithopone or titanium pigments, or may be used as the base upon which pigments are deposited by precipitation, electrodeposition, fuming or sublimation.  Thus, the particles of foliated glass may be coated with lithopone by adding them during the mixing of heated solutions of zinc sulphate and barium sulphide, and a similar procedure may be followed in making cadmium lithopone. Titanium pigments may be precipitated upon the glass particles instead of upon the usual barium sulphate base, or the particles may be coated with antimony vermilion precipitated from mixed solutions of antimony chloride and sodium thiosulphate.  The fumes of lead or other metal, or a sublimation of fine metallic particles may be deposited upon the glass. Specification 345,845 is referred to. According to the Specification as open to inspection under Sect. 91, other foliated materials such as mica, aluminium flake, brass flake, an aluminium silicate known as sigal, or pyroxylin in thin sheet form may replace the foliated glass, and soya bean oil, perilla oil or oticica oil may be used as the vehicle.  The particles of foliated base may be treated with phthalic anhydride or with alum solution, to increase the tenacity with which a pigment coating adheres to the particles.  The foliated glass may be incorporated with a synthetic resin to produce an insulating compound, may be mixed with asphalt, with or without a cement, and employed as a roofing material or a coating for shingles, or may be used, coloured or pigmented if desired, as a glaze for articles of pottery, brick, and tile.  It may also be mixed with resins or gums to provide resistant coatings for pipes, tanks, &c.  This subject-matter does not appear in the Specification as accepted.
