Wire coating composition

Claim 1

An article comprising a substrate having a composition coated on at least one surface thereof, said composition comprising an admixture of: a. 35 to 70 weight percent of an anhydride copolymer which is the reaction product of: (1) an alkyl or aryl substituted or unsubstituted unsaturated cyclic anhydride wherein each alkyl group contains up to 6 C atoms and the cyclic group contains 4 to 15 C atoms, and (2) an unsaturated C 10 to C 24 aliphatic hydrocarbon; b. 10 to 41 weight percent of a compatible, flexibilizing polymer which is selected from polyisobutylene and polymers of ethylene copolymerized with vinyl acetate, acrylate esters, methacrylate esters, and alpha-olefins, and c. 10 to 40 weight percent of a hydrophobic, compatible, fluoroaliphatic radical-containing composition, said fluoroaliphatic radical being a monovalent, fluorinated, aliphatic radical having 5 to 14 carbon atoms which can be interrupted by divalent O atoms or trivalent N atoms bonded to C atoms; said fluoroaliphatic radical-containing composition being capable of providing water-repellancy to said admixture, and d. up to 10 weight percent of a mercaptan compound.
