    摘要： The present invention relates to pulverent binders for powder coating compositions which contain oligo- and polyurethanes having (meth)acryloyl groups, are curable by means of high energy radiation and have an organic solvent content of less than 1 wt. %. The present invention also relates to a process for preparing these binders in the absence of an organic solvent and to their use in powder coating compositions for coating wood, metal, plastic, mineral and/or preprimed substrates.

    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.
