Filled epoxide resins are bonded to plastic or metal bodies by an epox - ide resin bonding agent which contains a stabiliser

Process for the bonding of filled epoxide resins to the surface of a body comprises (a) treating the surface of the body prior to chemically bonding to a bonding layer (b) preparing the bonding layer ready for bonding, and (c) contacting the bonding layer with the treated surface. The bonding layer consists of an epoxide resin containing a stabiliser which retains the epoxide resin in pliable form until the plastic body to be bonded is placed in position on the bonding layer. The plastic body is then fixed to the bonding layer while this layer is flexible. The body to which the filled epoxide resin is bonded may be a plastic body, e.g. polyethylene or polypropylene, or may be a metal body.
