ABSTRACT:
Polyisocyanate polyaddition products which are solid below 40.degree. C. and liquid above 125.degree. C., contain uretdione and urethane groups and have a content of at least 1 wt. % of urethane groups obtained from the reaction of dimeric diols with isocyanate groups; a method of producing the these products by the reaction of polyisocyanates containing uretdione groups with dimeric diols; and the use of these polyaddition compounds as the starting component in the manufacture of polyurethane plastics, particularly as the cross-linking component in thermally cross-linkable two-component polyurethane powder coating compositions.
