Abstract
Abstract This invention is addressed to the improvement in the bonding relationship of glass fibers with elastomeric materials in the manufacture of glass fiber-reinforced elastomeric products wherein individual glass fibers are treated with a composition including a polyamide, which is preferably a microcrystalline polyamide, a lubricant, an organo silicon compound coupling agent and a gel agent to form a thin coating on the individual glass fibers, and wherein the individually coated glass fibers may be further processed into glass fiber bundles and impregnated with an elastomer compatible material.
