Abstract
Abstract A composition for use in the treatment of glass fibers, and preferably in the treatment of glass fibers to form a size coating thereon to facilitate contact of the glass fibers with resinous and elastomeric materials in the manufacture of glass fiber reinforced resins and glass fiber reinforced elastomeric products wherein the size composition is formulated to contain, as the essential ingredients, a film-forming binder and an amino acid as a coupling agent. Bundles of glass fibers sized with the composition of this invention are particularly well suited for impregnation with an elastomer compatible material containing a resorcinol-aldehyde resin component and an elastomer component for use in the manufacture of glass fiber reinforced elastomeric products. Polyamines may also be used as coupling agents instead of the amino acids.
