At 115 ° C, then 36.6 hours of N-methylpy are added slowly Rolidone and 366.3 hours, ammonia (25% solution). After 1 hour, 100 hours of completely demineralized water are added at this temperature and again kept at 100 ° C for 2 hours. After cooling, 14.7 hours is added , titanium tetralactate. Thus obtained aqueous wire: the lacquer contains 54.1% of solid matter with running water in the stoma in the Ford funnel (4 mm) according to DIN 53.2 in 27 Co
    Lacquer with the use of a conventional furnace, for varnishing a 2.50 m long wire, is applied on a 00.5 mm copper wire in 8 strands and fired at 460 C. The traction speed is 20 m / min.
