ABSTRACT:
An aqueous sizing composition for at least partially coating a plurality of glass fibers can comprise at least one rosin, at least one coupling agent, and at least one lubricant. The rosin can be a chemically-modified rosin. A plurality of coupling agents can be included, including combinations of coupling agents that can provide for multi-resin compatibility and desirable fiber glass strand properties. An embodiment of a fiber glass strand at least partially coated with a sizing composition may have properties particularly suited for applications that do not utilize air jet weaving.
