Coating material comprising unsaturated polyester resins and vinyl ethers

摘要

The use of a composition which is liquid under standard conditions (20° C., 1 bar) as a coating material, wherein the composition comprises
a) an unsaturated polyester resin composed of α-olefinically unsaturated polycarboxylic acids, polyols, and optionally further compounds,b) compounds with vinyl ether groups (vinyl ethers for short), andc) optionally α-olefinically unsaturated polycarboxylic acids or their monoesters or diesters,wherethe sum of the double bonds of the α-olefinically unsaturated polycarboxylic acids from a) and optionally of the compounds c) to the double bonds of the vinyl ethers b) is in a molar ratio of 1.3:1 to 0.8:1.

1. A method of coating a surface, the method comprising contacting a surface with a composition which is liquid under standard conditions (20° C., 1 bar), wherein the composition comprises
a) an unsaturated polyester resin comprising, in reacted form, an α-olefinically unsaturated polycarboxylic acid, a polyol, and optionally a further compound, b) a vinyl ether compound, and c) an α-olefinically unsaturated polycarboxylic acid monoester or diester of a C1 to C10 alkanol or cycloalkanol, where a molar ratio of (i) to (ii) is in a range of 1.3:1 to 0.8:1, wherein (i) is a sum of double bonds of the α-olefinically unsaturated polycarboxylic acid of a) and the α-olefinically unsaturated polycarboxylic acid monoester or diester of c), and wherein (ii) is a sum of double bonds of the vinyl ether compound b).
