Abstract: The present invention relates to an improved method of forming a polyfluorocarbon coating on a razor blade cutting edge comprising the steps of subjecting a fluorocarbon polymer having a molecular weight of at least about 1,000,000 to ionizing radiation to reduce the average molecular weight to from about 700 to about 700,000; dispersing the irradiated fluorocarbon polymer in an aqueous solution; coating said razor blade cutting edge with the dispersion; and heating the coating obtained to melt, partially melt or sinter the fluorocarbon polymer.

Abstract: Improved razor blades and methods for producing the blades. The cutting edge regions of the blades include a solid adherent coating which is the residue of a heated mixture of a fluorocarbon polymer and a silane. The mixture is applied to the cutting edge regions of the blade and heated to a temperature sufficient to melt the fluorocarbon. The coatings achieved in the practice of the invention provide blades having improved shaving performance characteristics for the blade.
