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.

Abstract: Polymers on the basis of tetrafluoroethylene are produced in the presence of a redox system as catalyst consisting of a usual peroxidic compound as oxidizing component and a water-soluble nitrogen compound liberating in situ a diimine under the polymerization conditions. The polymers obtained can be processed, inter alia, into thick walled articles on a ram extruder or into large sintered block free from crack formation.
