Abstract

Binders which are hardenable by radiation or peroxides and are useful in coating compositions are compounds containing isocyanurate groups and olefinic double bonds produced by the reaction of components (a), (b) and (c) wherein PA0 (a) is a polyisocyanate component containing isocyanurate polyisocyanates which is PA1 (i) N,N',N"-tris-(isocyanatohexyl)-isocyanurate alone or in admixture with its higher homologs containing more than one isocyanurate ring or PA1 (ii) mixtures of the polyisocyanates (i) with up to 40 NCO-equivalent-%, based on the total component (a), of other polyisocyanates containing aliphatically or cycloaliphatically bound isocyanate groups; PA1 (b) is an olefinically unsaturated alcohol component comprising at least one hydroxyalkyl ester of acrylic acid or methacrylic acid; and PA0 (c) is a polyol component consisting essentially of a polyester polyol having an OH value of 80 to 350 based on (i) an acid component, of which at least 80 carboxyl equivalent-% is adipic acid, isophthalic acid or a mixture of both and (ii) a polyhydroxy component of which at least 70 hydroxyl equivalent-% is hexane-1, 6-diol; wherein component (c) amounts to 20 to 150% by weight, ba…
