Abstract: THE PRESENT INVENTION RELATES TO POLYTETRAFLUOROETHYLENE DISPERSIONS FOR COATING SURFACES OF METAL, GLASS OR CERAMICS. THE DISPERSIONS CONTAIN SOLUBLE ADDITIVES WHICH CONSISTS OF COMPLEX COMPOUNDS OF METAL HYDROXIDES, PREFERABLY COPPER-, CADMIUM- OR ZINC HYDROXIDE, WITH 2 TO 6 MOLES OF PRIMARY AS LIGANDS, OR HYDROXOZINCATES. THESE ADDITIVES IMPROVE THE POLYTETRAFLUOROETHYLENE COATINGS IN RESPECT OF ADHERENCE TO THE SUBSTRATE AND FREEDOM FROM CRACKS AND VOIDS.
