PCT No. PCT/EP94/00583 Sec. 371 Date Sep. 5, 1995 Sec. 102(e) Date Sep. 5, 1995 PCT Filed Mar. 1, 1994 PCT Pub. No. WO94/20966 PCT Pub. Date Sep. 15, 1994The present invention relates to solderable wire-coating compositions based on hydroxyl group-containing polyesters, blocked polyisocyanates, organic solvents and catalysts, which are characterized in that they contain A) from 7 to 25% by weight of hydroxyl group-containing polyesters, B) from 55 to 70% by weight of a fully blocked aromatic diisocyanate adduct or of a plurality of fully blocked aromatic diisocyanate adducts, C) from 0.1 to 3% by weight of catalysts, D) from 1 to 8% by weight of a polyol or of a plurality of polyols, and E) from 1 to 36.9% by weight of an alkylene carbonate or of a plurality of alkylene carbonates, the total weight of the wire-coating compositions in each case being 100% by weight. The present invention also relates to a process for the continuous coating of wires using the solderable wire-coating compositions described. |
