There are various ways to improve the adhesion between the SBR compound and the tire bead wire.

1. The bead must be ready by chemical treatment on to the surface.

2. One may adopt copper coating or zinc coating, followed by adhesive solution.  or by treatment with the primer and the adhesive solution.

3. The rubber compound may be incorporated with the adhesion promoters such as HRH dry bonding agents.

You can use polyurethanes  adhesives

Thanks a lot for the inputs..

The steel cord is coated with bronze, brass or zinc. Sulfur and sulfur compounds used for vulcanization of the rubber result in a good adhesion to copper or zinc. For this reason a relatively high amount of sulfur is used in these cases. Additional often cobalt naphthenate is added to improve the adhesion further but is has the disadvantage to worsen the stability of the tire against oxidation. Also additional phenol-formaldehyde resins (mixtures of urotropine with resorcine) improve the adhesion further.

Thanks for the suggestions. Highly helpful!

You can Also use the tackifying resin.

if you use resin , resin improve the tack property as well as improve the proccessiability and flow property

other solution you can use the non polor solvant to adhere purpose
