ABSTRACT:
The present invention provides aqueous secondary coating compositions adapted to coat a sized fiber strand, the compositions including a urethane-containing polymer and a blend of a halogenated vinyl polymer and an elastomeric polymer. Another aspect of the present invention is a generally tubular assembly having a reinforcement coated with a primary layer of a sizing composition including a fiber lubricant which provides the assembly with an electrical resistance of greater than about 750 megaohms per 152.+-.13 millimeters of length of the assembly and a secondary layer including a halogenated vinyl homopolymer and a urethane-containing polymer. Another aspect of the present invention is a fiber strand formed from a thermoplastic or thermosetting material having a primary layer including a halogenated vinyl homopolymer and a urethane-containing polymer. The present invention also includes strands coated with the above-discussed coatings and polymeric composites and assemblies reinforced with the same.
