ABSTRACT:
A process for polymer coating of narrow strands, for example, wires with a polymer, is disclosed whereby a rapidly reacting polymer formulation is sprayed onto the narrow strands whereupon it hardens in a very short period of time and another layer of strands is then placed atop the first which have now been coated with the polymer and a second layer of polymer formulation is sprayed on these strands, etc. The polymer formulation used comprises amine terminated polyethers of greater than 1500 average molecular weight, having greater than 50% of their average hydrogens in the form of amine hydrogens, a chain extender and an aromatic polyisocyanate.
