Abstract
Process for the preparation of coatings on wires or fiber-like materials, in which hydroxyl-containing polymers having a number-average molecular weight of 250 to 1,000, a hydroxyl number of 130 to 750 and an acid number of 0 to 150 are mixed in the liquid state with polyisocyanates having a number-average molecular weight of 200 to 2,000 in the liquid state immediately before application, so that 0.5 to 1.5 isocyanate groups are present for each hydroxyl and carboxyl group, and are fed to a wire or fiber-like material which is in a continuous forward movement in an amount which corresponds to that immediately consumed, and a device suitable for the process and comprising capillary tubes through which the mixture is fed to the wire or fiber-like material.
