Delayed hypopigmentation is a reason why some doctors dislike the long-term results of deep peels. Hypopigmentation after phenol peels is proportional to the depth of the peel, amount of the solution used, inherent skin color, and post-peel sun-related behavior. Complete avoidance of any sun exposure years after the peel creates ivory skin color.

F-BDAF Tg for various blend compositions, see Fig. 14. The microphase-separated morphology further manifests itself in the self-adhesion behavior of polyimide films derived from such mixtures. For mixture containing at least 25 wt% of the flexible component, peel tests of polyimide bilayer samples prepared by solution casting, bulk failure of the test specimens was observed. Since the flexible component contained fluorine, the samples could be examined by X-ray photoelectron spectroscopy to determine the surface composition. At only 10% loading, the flexible component comprised 100% of the top 75 A of the sample. The surface segregation of the flexible component is believed to be responsible for the adhesion improvements. 

As already mentioned, McKenna (7), Frissell (4) and Greenhoe (6) have characterized the gelation behavior of different plastisols by the temperature at which the film breaks on hot peeling from the metal surface. We found, however, that the temperature at which the film could be peeled from the foil varied depending on whether the peeling was carried out before or after the film had been allowed to cool (Figure 5). We do not consider that this type of transition point has any particular practical significance. 

The locus of failure in all PMDA-ODA/MgO cases is consistently a mixed mode type leaving ceramic on the polyimide failure surface, and leaving polyimide on the ceramic failure surface. APS application prior to polyimide coating does not change the failure locus or the peel strength behavior of these interfaces.
