Abstract

The invention relates to modified polyisocyanates, obtained by reacting at least one polyisocyanate (A) based on 1,5-diisocyanatopentane with at least one silane compound (B) which is reactive with respect to isocyanate groups. The invention also relates to a method for producing the modified polyisocyanates and to the use thereof as starting components in the production of polyurethane plastics, in particular as crosslinker components in polyurethane paints and coatings.
