    摘要: The invention relates to optionally solventless two-component polyurethane surfacers containing finely divided fillers in a high pigment volume concentration based on a polyfunctional isocyanate component (B) and a polyol component (A) which is liquid at room temperature and which consists of mixture components containing isocyanate-reactive hydroxyl groups with an at least predominant content of branched-chain polyols (A1) containing ester and ether groups, which contains at least a proportion of the finely divided fillers and, optionally, the additives and which, for application, is mixed with the isocyanate component (B) and applied as a mixture which can still be processed by shaping. To form a substantially waterproof, elastic multipurpose adhesive surfacer which combines high adhesive strength with high volume stability, the polyol component (A) contains oleopolyols having an OH functionality of at least 2 to about 3 as an additional mixture component (A2) and, if desired, low-viscosity monofunctional alcohols of distinctly oleophilic character, which are at least substantially involatile at room temperature, in admixture with component (A1) as another additional mixture component (A3).
