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:
L'invention concerne un procédé amélioré de formation d'un revêtement en polyfluorocarbone sur le bord tranchant d'une lame de rasoir, ce procédé consistant à soumettre le polymère de fluorocarbone ayant un poids moléculaire d'au moins 1 000 000 envrion à un rayonnement ionisant afin de réduire le poids moléculaire moyen d'environ 700 000, à disperser le polymère de fluorocarbone irradié dans une solution aqueuse, à revêtir le bord tranchant de la lame de rasoir avec la dispersion, et à chauffer le revêtement obtenu afin de fondre partiellement ou fritter le polymère de fluorocarbone.
