    Abstract: An aqueous coating composition which contains at least one water-dispersible polyurethane resin containing air-drying groups and optionally further binder resins and conventional (paint) additives, characterised in that the polyurethane resin contains units derived from (A) polyisocyanates, (B) polyols containing air-drying groups, optionally (C) polyols containing no air-drying groups, (D) compounds containing at least two groups which are reactive towards isocyanate groups and containing at least one group which is capable of forming anions, (E) monoalcohols containing air-drying groups, and/or (F) compounds which are different from (B), (C), (D) and (E) and contain at least one group which is reactive with NCO groups. This coating composition has excellent pigment compatibility, and the coatings produced therefrom provide good corrosion protection and have good mechanical properties, even without addition of a siccative.

    Abstract: Hydrophilic polyurethane-polyureas (I) are obtd. by reacting (A) polyisocyanate(s) with (B) fatty acid deriv(s). which is/are reactive towards (a), (C) opt. a cpd. with more than 2 OH and/or COOH gps., (D) a polyalkylene glycol with a mol. wt. of 500-10,000 and (E) a cpd. with active H atom(s) which react more rapidly than water with NOC gps., with a mole ratio of (NCO gps.):(all NCO-reactive H atoms in A-E) = (0.5:1)-(2:1). Pref. mole ratio of (NCO gps.):(H atoms in OH and amino gps. in all components A-E) = (0.7:1)-(1.5:1); amts. of co-reactants are 0.1-1 mole (B), 0-0.8 mole (C), 0.1-0.8 mole (D) and 0.01-0.3 mole (E) to 1 mole (A). (B) comprise opt. unsatd. cpds., pref. fatty alcohols, fatty amines, or ethoxylated fatty alcohols or amines contg. 1-30 ethylene oxide (EO) units, esp. ethoxylated fatty alcohols with 1-20 EO units, or reaction prods. of fatty acids with polyols which may also contain amino gps., or reaction prods. of fatty acids and mono-epoxides. (C) is a bis-hydroxy-alkanecarboxylic acid, pref. dimethylolpropionic acid (DMPA).

    Abstract: A fluorine-containing powder coating is described, comprising a) a crosslinkable, fluorine-containing copolymer, composed of a vinyl ester of a highly branched carboxylic acid, whose acyl radical has 9 carbon atoms and is composed of isomers having two quaternary carbon atoms, to which 0 to 80 mol% of isomers which contain one quaternary carbon atom together with at least one tertiary carbon atom in the acyl radical are admixed, of a vinyl monomer containing OH groups, and of a fluoroolefin of the general formula CF2=CFX, in which X=F, a perfluoroalkyl radical having 1 to 8 carbon atoms or Cl, and b) 20 to 60% by weight of a crosslinking agent suitable for powder coating formulations. Preferably, the latter is a blocked polyisocyanate.
