摘要：A binder composition is described which is suitable for coating compositions andcontains one or more unsaturated polyesters having an acid number of from 5 to 60 mgof KOH/g, a hydroxyl number of from 50 to 200 mg of KOH/g, a weight-averagemolecular weight (Mw) of from 500 to 3000 g/mol and a content of from 0.8 to 1.2ethylenic double bonds per 100 g of polyester, which are obtainable by reacting A) oneor more alpha,beta-ethylenically unsaturated dicarboxylic acids or their anhydrides, B)one or more hydroxy-functional allyl ethers, without the addition of other polyols, and C)one or more ethylenically unsaturated compounds containing an oxirane group in themolecule, in a molar ratio of A) : B) : C) = (2 to 4) : (2 to 4) : (0.5 to 1.8). The composition isparticularly suitable for filling compounds (trowelling compositions) and fillercompositions which dry rapidly even at low temperatures.
