GLASSFIBER TREATED WITH NONNDISCOLORING SIZE AND SIZING AGENT FOR GLASSFIBER

摘要

A non-discoloring glass strand size comprises a polyurethane latex emulsion produced by the chain extension of an NCO-terminated prepolymer. The prepolymer is prepared by the reaction of an aliphatic or cycloaliphatic diisocyanate with a polyalkylene ether polyol and is particularly suitable for glass incorporated in polyamide resins.
