Abstract
A process and device for the preparation of coatings on wires or fiber-like materials by mixing one or more polymers which contain carboxyl and/or amide groups (A) and with at least two carboxyl and/or amide groups, a hydroxyl number of less than 130 and a number average molecular weight of 200 to 5000, in the liquid state, with one or more polyisocyanates (B) with at least two free isocyanate groups in the molecule and a number average molecular weight of 200 to 3000, in the liquid state, and optionally one or more other components (C) which are normally present in lacquers, in the liquid state, continuously immediately before application in a ratio such that 0.5 to 5.0 isocyanate groups are allotted to each carboxyl group or that 0.02 to 2.0 isocyanate groups are allotted to each amide group, wherein the components A, B and/or C may contain one or more catalysts, and with continuous supply of the mixture to each individual wire or fiber-like material, which is in continuous motion, in an amount which corresponds to immediate consumption.
