摘要: A binder composition suitable for coating agents is described, that contains one or more unsaturated polyesters with an acid number of 5-60 mg KOH/g, a hydroxyl number of 50-200 mg KOH/g and a weight-average molecular weight (Mw) of 500-3000 g/mol, that are obtainable by reaction ofA) one or more alpha,beta-ethylenically unsaturated dicarboxylic acids or their anhydrides,B) one or more hydroxy-functional allyl ethers andC) one or more ethylenically unsaturated compounds with an oxirane group in the molecule,in the molar ratio of A):B):C)=(2 to 4):(2 to 4):(0.5 to 1.8). The composition is suitable in particular for filling putties and filling compounds that dry rapidly, even at low temperatures.

摘要: Previous coating materials lead to the formation of bubbles at high layer thickness and when drying by heating. The new coating materials are intended to be bubble-free when dried at higher layer thicknesses.Aside from pigments and/or extenders, the coating material contains solvents and, if necessary, conventional paint auxiliaries in a vehicle mixture, comprising essentially 60-75% by weight of a hydroxy-functional copolymer, 1-5% by weight of an ester-soluble nitrocellulose and 25-35% by weight of difunctional or multifunctional polyisocyanate. It can be cured without forming bubbles even when applied in thick layers.Use as primer and filler.
