Claim 20:
21. A method of activating a surface of a plastics substrate formed from polyphenylene sulfide (PPS), for subsequent bonding,
the method comprising the step of applying copper acrylate to the surface and then exposing the surface to actinic radiation wherein the actinic radiation
includes radiation with wavelength in the range from about 10 nm to about 1000 nm; and
the energy of the actinic radiation to which the surface is exposed is in the range from about 2 J/cm2 to about 240 J/cm2 for subsequent bonding with acrylic adhesive optionally wherein the surface is treated with (meth)acrylate, prior to exposing the surface to the actinic radiation,
or the energy of the actinic radiation to which the surface is exposed is in the range from about 5 J/cm2 to about 312 J/cm2 for subsequent bonding with epoxy adhesive.
