adhesive energy and rubber coverage values are obtained in the optimized system. A
wire coat compound containing silica (Hi-Sil®233), organocobalt and a
resorcinol/formaldehyde donor resin system is also studied. Results are compared to
those based on wire coat formulations of tire manufacturers using specialized
ingredients to obtain adhesion improvement.
