Abstract

This invention relates to solvent-free two-component polyurethane reactive adhesives comprising PA1 (A) a polyisocyanate component based on diphenylmethane diisocyanates, PA1 (B) a water-containing polyol component having a maximum of three OH groups, a water content of 0.25 to 2.0 wt. %, and an OH value of 300 to 600, and optionally PA1 (C) auxiliary substances and additives, PA1 wherein component (A) and component (B) are present in proportionate amounts such that the isocyanate index is 120 to 250. These adhesives are used for producing sandwich-type interior panelling for vehicles.
