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

Method and composition for improving lubricity, abrasion resistance, and lowering the coefficient of friction of substrates such as photographic film, magnetic surfaces and other recording elements by applying to such substrates a solution comprising tetrafluoroethylene telomer and a copolymer of vinyl chloride and trifluorochloroethylene in a volatile solvent, drying and removing the excess, and substrates so lubricated.

Method and composition for lubricating and lubricated substrates

Method and composition for improving lubricity, abrasion resistance, and lowering the coefficient friction of subtrates such as photographic film, magnetic surfaces and other recording elements by applying to such substrates a solution comprising tetrafluoroethylene telomer and a copolymer of vinyl chloride and trifluorochloroethylene in a volatile solvent, drying and removing the excess, and substrates so lubricated.
