摘要： The invention relates to coating substances that are free of covering pigments, contain solvents, and can be hardened thermally or by actinic radiation, said substances also containing: (A) at least one constituent selected from the group consisting of low-molecular, oligomer and polymer binding agents, cross-linking agents and reactive diluents that can be hardened thermally and by means of actinic radiation; and (B) between 0.01 and 4 wt. %, in relation to the coating substance, of dispersed, synthetic polyamide wax particles. The invention also relates to a method for producing said substances and to the use thereof for producing single-layer and multi-layer varnish, and chromophore and/or effect-generating multilayer paint, or as adhesives and sealing materials.

摘要： Disclosed are coating materials comprising (A) at least one (meth)acrylate (co) polymer which contains hydroxyl groups and has a hydroxyl number of 100 to 250 mg KOH/g, an acid number of 0 to 35 mg KOH/g, a number average molecular weight Mn of 1'200 to 20'000 dalton and a maximum glass transition temperature of +70 °C, (B) at least one compound that contains carbamate groups and hydroxyl groups and has a hydroxyl number of 10 to 150 mg KOH/g, a carbamate equivalent weight CEW of 250 to 700 g/equivalent, and an equivalent ratio of hydroxyl groups to carbamate groups ranging between 1:20 and 1:0.5, and (C) at least one aminoplastic resin. (I) At least 10 equivalent percent of the hydroxyl groups contained in the (meth)acrylate (co)polymers (A) and/or in compounds (B) are primary hydroxyl groups, and (II) the coating material is provided with a storage module (E') in the rubber-elastic range of at least 1.5*107 Pa after hardening, the storage module E' being measured on homogeneous free films having a layer thickness of 40 ± 10 µm by means of dynamic mechanical thermal analysis (DMTA). Also disclosed are a method for producing the inventive coating materials and the use thereof.
