A single adhesive composition for use in bonding more than one class of rubber polymer to textiles, in particular nylon and polyester fabric. The composition comprises an aqueous mixture of: a) about 85 to about 90 weight % polychloroprene latex; b) about 2 to about 6 weight % of at least one prepolymer of resorcinol with formaldehyde; c) about 4 to about 8% by weight of at least one blocked diisocyanate compound; and d) sufficient water to adjust the solids content of the mixture to about 15 to about 40% by weight; wherein the percentage of solids add-on on fabric treated with the composition ranges between about 5 and about 20% based on the weight of the untreated fabric. The preferred blocked diisocyanate compound is caprolactam blocked methylene-bis-(4-phenylisocyanate). The end-products that are contemplated for the present invention include, but are not limited to, diaphragms, molded articles, V-belt covers, conveyor belts, bead wraps for tires, hose wrap, dodge couplings and the like.
