Abstract: A connecting composition and a scaling coating for wire or cable insulation is disclosed. The connecting composition comprising a PVDF copolymer and a solvent. The solvent comprises cyclic ketone, wherein the weight percent of PVDF copolymer is from 20 to 40 wt. %, preferably 20 to 35 wt. % based on the total weight of PVDF copolymer and solvent. The PVDF copolymer comprises one or more comonomers and at least 75 wt. % vinylidene fluoride units, preferable at least 80% vinylidene fluoride units and has a melt viscosity of 2 to 12, preferably 4 and 10 kPoise at 230° C. and 100 s−1.
