摘要:
Method and composition for improving lubricity, abrasion resistance, and lowering the coefficient 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.
摘要:
Release and lubricating composition for avoiding seizure between molten glass and metal molds for forming glass articles, for minimizing wear between mold sections and for improving the pack of glassware, comprising, a dispersion of graphite in a polyimide resin, molds having such composition coated thereon, and a method of applying the composition to molten glass contacting surfaces comprising dispersing the composition in a solvent, applying the dispersed composition to the glass contacting surface and then baking the coating at an elevated temperature.
