Reflectance infrared spectroscopy can therefore yield chemical information about substrate surface composition and, important for the study of adhesion, interaction between adsorbed species and substrates. [Pg.188]

The real power of reflectance IR is the ability to study polymer/metal or more specifically adhesive/adherend, primer/adherend and coating/substrate interfaces. Boerio et were [Pg.189]
