In order to use these analytical methods for a description of the phase boundary between rubber, bonding agent and metal, this boundary first has to be set free.
To facilitate rupture and obtain an even fracture surface at the bonding agent/metal interface, a standard bonding agent was applied to a ground metal surface.
No primer was used because the main objective-of the test was to analyze the interaction between the rubber and the bonding agent.
The elements determined by analysis are typical components of a bonding agent, namely chlorine and bromine, as well as zinc and sulfur which are typical for the rubber matrix.
At room temperature Successful bonding at room temperature has been accomplished with two classes of adhesives - PVC pipe cements and second generation acrylics (ITW B 0550 system), using the following procedure:
However, this type of bonding is difficult and requires a very precise technique.
With solvent adhesives In laboratory tests, hot bonding of Alcryn to polychloroprene has been accomplished with the EP 4802-75 adhesive system, using the following procedure:
