A polyurethane molding composition, cross-linkable by silane polycondensation, comprises an alkoxysilane functionalized polyurethane, a basic filler, a reaction product of an aminosilane with a maleic or fumaric acid ester, an organometallic compound and optionally other additives. A polyurethane molding composition (I), cross-linkable by silane polycondensation, comprises: (A) an alkoxysilane functionalized polyurethane having end groups of formula (1); (B) a basic filler; (C) a reaction product of an aminosilane of formula (2) with a maleic or fumaric acid ester of formula (3); (D) an organometallic compound; and (E) optionally other additives. An Independent claim is included for a process for the production of (I) by mixing components (A), (B), (C), (D) and optionally (E), under the exclusion of moisture, followed by the addition of (F). R<3>OOC-CH=CH-COOR<3> (3) R<1> = 1-24C organic group; R<2> = H or aminoethyl group; R<3> = 1-12C alkyl; n = 2-4; X,Y,Z = an organic group, whereby at least one of X, Y, Z is a methoxy or ethoxy group
