Claim 26:
27. A method of activating a surface of a plastics substrate formed from: polyetherimide (PEI) for subsequent bonding,
the method comprising the steps of
treating the surface with copper acrylate, prior to exposing the surface to actinic radiation,
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 3 J/cm2 to about 30 J/cm2 for subsequent bonding with anaerobic adhesive.
