Abstract

The use of partly dehydrated castor oil with an OH no. of 90-130 mg KOH/g (I) as a component of polyol mixts. for the prodn. of aq. polyurethane (PU) dispersions is claimed. Also claimed are coatings for wood, plastic, metal, glass, leather, textiles, paper and concrete, based on these aq. PU dispersions. Pref. (I) is prepd. by dehydration of castor oil in the presence of acid catalysts, e.g. H2SO4, acid anhydrides, acidic oxides etc. (see e.g. Farbe und Lacke, 57, 149, 1951 etc.).
