Claim 1
Independent Claim
94 words
A METHOD OF COATING A SURFACE OF A SOLID SYNTHETIC ORGANIC HIGH POLYMER WITH A THIN ADHERENT FILM OF POLYTETRAFLUOROETHYLENE WHICH COMPRISES SPRAYING THE SURFACE WITH AN AQUEOUS DISPERSION OF POLYTETRAFLUOROETHYLENE CONTAINING A VOLATILE ORGANIC SOLVENT FOR THE HIGH POLYMER UNDER CONDTIONS WHICH RESULT IN SPRAY-COATING THE SURFACE WITH A SMALL AMOUNT OF A VOLATILE ORGANIC SOLVENT FOR THE HIGH POLYMER WHICH IS SUFFICIENT TO CAUSE THE SURFACE TO BECOM TACKY AND WIN A WATER-MOIST, NON-SPECULAR, THIN FILM OF POLYTETRAFLUOROETHYLENE OF NOT OVER 0.2 MILS THICKNESS AND DRYING THE FILM IN THE AMBIENT AIR
