Abstract
The present invention relates to secondary coating compositions for glass fibers, glass fibers at least partially coated with the residue of a secondary coating composition, and cable assemblies comprising glass fibers at least partially coated with the residue of a secondary coating composition. A secondary coating composition can comprise a polyurethane and a wax. A secondary coating composition can further comprise a cross-linking agent. A cable assembly can comprise a conductor, a protective layer, and glass fibers at least partially coated with the residue of a secondary coating.

A secondary coating composition for at least partially coating glass fibers, comprising:
- a polyurethane in an amount greater than about 85 weight percent of the secondary coating composition based on total solids;
- and
- a wax.
A secondary coating composition for at least partially coating glass fibers, the major constituents including:
- a polyurethane in an amount greater than about 85 weight percent of the secondary coating composition based on total solids;
- and
- a wax.
A secondary coating composition for at least partially coating glass fibers, the major constituents including:
- a polyurethane in an amount greater than about 85 weight percent of the secondary coating composition based on total solids;
- a wax;
- and
- a cross-linking agent.
A fiber glass strand adapted to exhibit reduced blistering and fewer breakouts during co-extrusion, comprising at least one glass fiber at least partially coated with a secondary coating composition, the major constituents including:
- a polyurethane in an amount greater than about 85 weight percent on a total solids basis;
- and
- a wax.
