Abstract: The present invention relates to terpene derivative compounds and rosins and sizing compositions comprising such compounds. Compounds of Formula (I) are disclosed in addition to rosins and sizing compositions comprising compounds of Formula (I). Fiber glass strands comprising a plurality of glass fibers at least partially coated with sizing compositions comprising compounds of Formula (I) are also disclosed.

Abstract: An embodiment of a sizing composition for glass fibers comprises a starch, a nonionic lubricant, and a silane comprising at least one amine and at least one aryl or arylene group. Embodiments of fiber glass strands comprise at least one glass fiber at least partially coated with a sizing composition of the present invention. Embodiments of fiber glass strands can have tensile strengths that make the fiber glass strands desirable for certain processes, applications, and/or end uses.

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.

Abstract: The present invention provides a glass fiber product having particles adhered to at least one fiber of the product, where the size and amount of particles is effective to reduce the tackiness of the glass fiber product and optionally effective to reduce interfilament bonding, and composition, and method for forming the same.
