Peel strength values of sodium‐etched poly(tetrafluoroethylene) film bonded to polyurethane substrates have been monitored and found to decrease as a function of exposure to ultraviolet radiation. Attenuated total reflectance (ATR) spectra were monitored on unbonded sodium‐etched poly(tetrafluoroethylene) surfaces for the same environmental aging conditions and were found to vary significantly in the region of 1650 cm −1 . Techniques are proposed to retard UV‐initiated etch degradation and thereby prolong bond integrity.
