Aqueous size compositions for glass fibers including a film former, coupling agent and crystalline pentaerythritol, which are particularly suitable glass fiber reinforcements for filament winding and pultrusion.

Glass size compositions and glass fibers coated therewith

An aqueous size composition has been developed for glass fibers produced for molded products having appearance surfaces known as Class A surfaces. The size contains a cure stable polyester emulsion and a static insensitive lubricant system. The resulting coated glass fibers are especially useful in improving processability and product uniformity of SMC applications.

Size compositions for glass fibers

A cure stable polyester emulsion for use in an aqueous size composition has been developed for glass fibers produced for molded products having appearance surfaces known as Class A surfaces. The size contains a cure stable polyester emulsion and a static insensitive lubricant system. The resulting coated glass fibers are especially useful in improving processability and product uniformity of SMC applications.

Polyester emulsion

Cocoa amine acetate and a polyamide condensate, in combination as a lubricant in a glass size, result in glass strands exhibiting less fuzz than does glass sized with a size containing either of the two components, individually.
