Abstract
Abstract This invention is addressed to the treatment of glass fibers in the establishment of a more secure bonding relationship between glass fibers and elastomeric materials in which individual glass fibers are coated, or bundles of glass fibers are impregnated with a blend of an alkaline elastomer latex and a resin prepared by reaction of resorcinol and an aldehyde in the presence of an amino silane or a resorcinolato silane. Use can also be made of a resin prepared by reaction of melamine or urea and an aldehyde in the presence of an amino silane.
