Carboxy Terminated Liquid Natural Rubber (CTNR) was
prepared by photochemical reaction using maleic anhydride and masticated
natural rubber (NR). The use of CTNR as an adhesive in bonding rubber to
rubber and rubber to metal was studied. The peel strengths and lap shear
strengths of the adherends which were bonded using CTNR were determined.
The effect of using a tri isocyanate with CTNR in rubber to metal bonding was
also studied. It is found that CTNR can effectively be used in bonding rubber to
rubber and rubber to mild steel.
