Sizing composition to yield sized glass fibers with improved UV stability

Abstract

Sizing compositions, sized glass fiber strands are used to produce reinforced polymeric materials that have improved UV stability while maintaining good physical properties. The sizing composition, sized glass fiber strands and reinforced polymeric materials having sized glass fiber strands involve the use of materials in the sizing composition, such as polyurethane polymers, ureidofunctional silanes, aminofunctional silanes, lubricants and processing aids. One particular aspect of the present invention has materials associated with the sizing composition, sized glass fiber strands and reinforced polymers such as polyamides, polyethyleneterephthlate, polybutyleneterephthlate, polystyrenics, thermosetting esters, and chemically coupled polypropylene that are thermoplastic, aliphatic, polyurethane polymer dispersions, ureidofunctional silane, gamma-aminopropyltriethoxysilane, a lubricant modified gamma-aminopropyltriethoxysilane, dibutyphthalate, polyalkylene polyol lubricant, and a polyester film former.
