    摘要： The present invention relates to a process for preparing urethanes containing (meth)acryloyl groups that are suitable as binders for powder coatings by reacting a polyisocyanate component with a hydroxyl group-containing component that contains at least one compound additionally containing (meth)acryloyl groups in a melt of compounds containing (meth)acryloyl groups, which are crystalline in the solid state and have a melting point of 30 to 100° C. and a dynamic viscosity at 111° C. of less than 10 Pa·s, at elevated temperature until the NCO content has dropped below 0.5 wt. %. The present invention also relates to the use of these urethanes as binders for powder coating compositions for coating substrates made of wood, metal, plastics or mineral substances, which may have been primed.

    摘要： A process for preparing polyisocyanate-modified polycarboxylic acids by conversion of anhydride-group-free polycarboxylic acids with isocyanate-functional compounds. The process includes reacting A) an anhydride-group-free polycarboxylic-acid component with B) an isocyanate-functional component having an (average) isocyanate functionality of at least 1.8, at an equivalent ratio of carboxylic acid groups to isocyanate groups of from 1.2:1 to 120:1. The polyisocyanate-modified polycarboxylic acids are solid below 40° C. and liquid above 130° C., and have an average carboxylic acid functionality of at least 1.8, a content of free carboxylic acid groups of from 4.0 wt. % to 80.0 wt. % and a content of amide groups of from 0.4 wt. % to 32.5 wt. %.

    摘要： Polyaddition compounds containing uretdione groups prepared by reacting uretdione polyisocyanates formed from diisocyanates having exclusively secondary- and/or tertiary-attached isocyanate groups with a molar fraction of isocyanurate structures, based on the sum of uretdione groups and isocyanurate groups, of not more than 10%, with compounds reactive towards isocyanates. The polyaddition compounds can be use as a starting component in the preparation of polyurethane plastics, in particular as crosslinkers for heat-crosslinkable powder coating materials. The compounds may be used as starting components in the preparation of moldings and shaped parts, and as starting components in the preparation of coating materials and coatings.
