Abstract
Abstract Glass fibers coated with a blend of a resorcinol-aldehyde resin, an elastomer and a combination of organo silicon compounds formed of (1) an amino-substituted organo silane and/or its hydrolysis product and an organo silicon compound containing at least one beta-haloalkoxy group formed by reaction of a halosilane, a monoepoxide and a diepoxide.
