Internally-blocked polyurethane crosslinkers based on the uretdione of isophorone diisocyanate (IPDI) and hexamethylene diisocyanate (HDI) will be introduced. The principal structures and the performance properties of different products will be described. Besides the use in conventional high-gloss coatings, the possibilities will also be pointed out for special uretdione adducts for coatings with greater chemical resistance, specifically solvent resistance, or in the preparation of matte surfaces.
