A composition and method of preparation are herein described for molten release and parting compositions adaptable for use in glass-forming operations. The novel composition comprises an aqueous dispersion of a mixture of a solid lubricant, a water-soluble silicate binder, a setting agent, and a water-soluble phosphate. A preferred composition comprises a mixture of flake graphite, boron nitride, sodium silicate, zinc oxide and potassium phosphate tribasic.

Release coating for glass manufacture

Leader strip for motion picture films is described which is composed of a substrate of cellulose acetate or polyester, a gum-removing layer comprising an organic binder selected from the group consisting of cellulose esters, polyurethanes, polyacrylonitrile, copolymers of acrylonitrile and vinylidene chloride, and epoxy resins, a gum-shearing agent of finely divided polymeric particles, said agent being bonded by the organic binder to the substrate, said gum-shearing agent being a member selected from the group consisting of polyesters, polyamides, polyimides and polyolefins, said polymeric particles having a size less than about five mils.
