ABSTRACT:
Radiation cured compositions having improved abrasion resistance and cure response are made from blends of the reaction product of a diisocyanate, a hydroxyalkyl acrylate and a polyether diol with the reaction product of a diisocyanate, a hydroxyalkyl acrylate and a polyether triol wherein the average acrylate functionality of the blends is from about 2.4 to about 2.6. Such cured compositions are useful as coatings for various substrates.
