| titleOfInvention | PROCEDURE FOR OBTAINING A COATING AGENT. |
| abstract | Procedure for obtaining a coating agent characterized by using a) 10 to 90 parts by weight of a low molecular weight polytetrafluoroethylene, with a melt viscosity of 101 to 108 Poise (measured with the high pressure capillary viscometer at 380ºC), a specific surface area of 1 to 40 m2/g (measured by the BET method), and an average particle diameter of 0.1 to 50 μ, b) 90 to 10 parts by weight of a polymer containing tricetoimidazolidine rings and with repeating units of the formula **(See formula)** in which R represents a mono to trinuclear, bi to quadrivalent aromatic radical, the aromatic radicals being able to be also quinones, and in polynuclear systems the aromatic radicals can be united to each other by means of aliphatic radicals or heteroatoms; the aromatic radicals may also be optionally substituted by alkyl, cycloalkyl, alkoxys, aryl or monovalent functional radicals, while R'has the aforementioned meaning for R', or means an aliphatic or cycloaliphatic hydrocarbon radical, R'being able to be interrupted by one or more of the following groups: b1) amido, imido and/or amidoimido groups, obtained by introducing polycarboxylic acids, the ratio of the molar equivalents of polycarboxylic acid and polyisocyanate being equal to q: (q + 1), and c = 1 to 40, b21) chelate-forming azo and/or azomethine groups, metal chelates of said azo and/or azomethine groups, the ratio between the molar equivalents of the oxamidic ester and of the chelates and/or metal chelates being equal to (2 to 94): (0.1 to 50), at the same time as the sum of the oxamidic ester, chelate or chelate-forming, as well as possibly existing polycarboxylic acids, always amounts to 100 mol%, and is also n an integer from 1 to 70, and c) an aprotic organic solvent, which has a surface tension of> 30 dyn/cm, in an amount by weight 0.43 to 100 times the amount by weight of component b), possibly up to 80% of the amount by weight of this aprotic solvent with a surface tension of> 30 dyn/cm be replaced by another organic solvent, which does not need to meet at least one of these two conditions, although said other organic solvent must have a lower boiling point than the aprotic solvent.
