ABSTRACT:
An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, a stabilized colloidal silica sol, and a heat reactable resorcinol-formaldehyde resole, in certain amounts, is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.
