Rubber to metal adhesion in rubber to metal parts is of great importance. The optimum performance of this type of adhesion depends on the adhesion strength between rubber compound and metal surface and the consolidation of the compound. Resin additives and the presence of silica particles play a different role in adhesion improvement. Peel90 tensile strength and adhesion tests have been used to evaluate the effect of additives. According to the results, the presence of 15 phr of phenol formaldehyde resin has been coused to increase rubber to metal adhesion up to 17% but a reduction of 43% in the tensile strength of compound. On the other hand, it was observed that the presence of 15 phr HMMM resin along with phenol formaldehyde resin not only could improve rubber to metal adhesion up to 137%, but also decreased the loss of tensile strength of the rubber mixture to 12%. This is while the addition of 5 phr aerosol along with these resins could increase the adhesion to 175%. In this state, tensile properties have only drop out 3%.
