ABSTRACT:
A storage-stable, substantially NCO-free urethane urea acrylate which after radiation curing forms strongly adhering, solvent resistant, wear resistant coatings containing isophorone diisocyanate (IPDI) or adducts thereof which have been partially acrylated with one or more hydroxyacrylates to the extent of about 10-25 equivalent %, which material subsequently has been reacted to the extent of about 10-75 equivalent % with one or more polyhydroxy compounds, wherein the remaining NCO equivalents have been fixed with urea bonds with one or more primary or secondary diamino compounds having about 2 to 18 carbon atoms.
