A composition suitable for sizing of glass fibers is disclosed. The composition contains water dispersible, water-soluble or water emulsifiable resin selected from the group consisting of polyepoxide, polyester, polyvinyl acetate, polyacrylate and polyurethane, water, an organofunctional silane, and a nucleating agent. Optional components include emulsifiers, lubricants, wetting and anti-static agents. Glass fibers sized with the composition are suitable for preparing composites having improved mechanical properties. |
