ABSTRACT:
The present invention relates to polyurethane layers having higher surface energy. These polyurethane layers are formed on a substrate from a reactive mixture, and comprised of A) a compound containing isocyanate groups, B) an organic compound containing isocyanate-reactive groups, and C) at least one material selected from the group consisting of 1) reactive non-ionic polar materials, 2) reactive ionic polar materials, 3) non-reactive polar materials, and 4) mixtures thereof. Polyurethane layers such as these have been found to have improved adhesion and wet-out properties when used as precoat layers for carpet backing.
