Beschreibung
Zusammenfassung:	1512495 Non-stick polymer coated articles SEB SA 22 June 1976 [11 July 1975] 25950/76 Heading C3R 5 to 100 micron non-stick bonded coatings are formed on metal or glass articles, e.g. cooking utensils, are formed by applying to the degreased surface thereof a composition containing powdered PTFE and an organic solvent solution of a polyamide-imide resin of the formula where R is aliphatic and n indicates a degree of polymerization such that the resin is soluble in the solvent, and heating the coated surface at 220 to 260‹ C. for 10 to 15 minutes to crosslink the resin. Such coatings are harder and thus more abrasion resistant than plain PTFE coatings especially at higher temperatures, e.g. 200 to 300‹ C.
