Abstract: The present invention relates to polyester polyols comprising units derived from a) at least one COOH group or derivative thereof carrying component or mixture of components (A) comprising at least one compound carrying two COOH groups or derivatives thereof (A1), b) at least one OH group carrying component or mixture of components (B) comprising (i) at least one compound carrying three OH groups selected from the group consisting of 1,3,5-tris(hydroxymethyl)isocyanurate, 1,3,5-tris(2-hydroxyethyl) isocyanurate, 1,3,5-tris(2-hydroxyisopropyl)isocyanurate, 1,3,5-tris(2-hydroxypropyl)isocyanurate and 1,3,5-tris(2-hydroxybutyl)isocyanurate (B1), (ii) at least one compound carrying two OH groups selected from the group consisting of 1,1-bis(hydroxymethyl)-cyclohexane, 1,2-bis(hydroxymethyl)-cyclohexane, 1,3-bis(hydroxymethyl)-cyclohexane, 1,4-bis(hydroxymethyl)-cyclohexane, 1,1-bis(hydroxyethyl)-cyclohexane, 1,2-bis(hydroxyethyl)-cyclohexane, 1,3-bis(hydroxyethyl)-cyclohexane and 1,4-bis(hydroxyethyl)cyclohexane (B2), (iii) optionally at least one compound or polymer carrying at least three OH groups, which is different from B1 (B3), and (iv) optionally at least one compound or polymer carrying two OH groups, which is different from B2 (B4), and c) optionally at least one compound carrying at least one OH group and at least one COOH group or a derivative thereof (C), and to organic-solvent based two-component coating compositions comprising a) a first component (K1) comprising (i) at least one polyester polyol of the present invention and (ii) optionally at least one polymer carrying more than one OH group, which is different from the polyester polyol of the present invention (D), and b) a second component (K2) comprising (i) at least one compound, oligomer or polymer carrying more than one N═C═O group or blocked N═C═O group (F).

Abstract: The present invention relates to fast-drying, hard-elastic, scratch-resistant, and robust two-component polyurethane coating compositions, to their use, and to coating methods. Synthesis components in the coating compositions comprise polyisocyanate, hydroxyl-containing poly(meth)acrylate polyol, and certain branched polyester polyols, obtainable by polycondensation of hexahydrophthalic anhydride, trimethylolpropane, and optionally further components.
