We have a general interest in the adhesion of
natural rubber compounds to steel, in particular
making use of a widely used bonding system,
Chemlock 211 primer and Chemlock 220 adhesive.
One important aspect of the bonding process is the
interaction between a compounded rubber and the
adhesive. Both components of the bonding system
are complex formulations. However, it has been
suggested that a significant component of the
adhesive is a chlorinated rubber [2]. We have some
spectroscopic evidence that is in agreement with this
and have therefore studied the interactions that occur
within a simple model consisting of natural rubber
and a chlorinated natural rubber.
