ABSTRACT:
An aqueous alkaline dispersion of a rubber latex and dihydroxy-phenol-aldehyde resins consisting essentially of resorcinol-aldehyde resins and catechol-aldehyde resins is useful in forming an adhesive bond between reinforcing materials such as nylon and rubber compounds. It is essential that the catechol-aldehyde resin be made separately from the resorcinol-aldehyde resin with which it is later mixed in solution. The dispersions of this invention result in improved aged adhesion and lower fabric stiffness than the older resorcinol-formaldehyde latex dispersions.
