Aqueous dispersions of polymers of tetrafluoroolefin and tetrafluoroolefin/hexafluoropropylene containing other film-forming materials such as polyamide acid salts or polymeric quaternary hydroxides blended with nitrogen-resins and articles coated or impregnated with these dispersions are provided. n Coatings prepared from such dispersions provide lubricity, release properties, chemical and high temperature resistance, and electrical insulation for a wide variety of substrates such as metals, ceramics and the like. |
