Abstract
Adsorption experiments have been carried out to understand the interac tions responsible for UV light stabilizer adsorption on pigments in co atings. Light stabilizer adsorption on various pigments was studied in xylene solutions to eliminate potential interference from the cure pr ocess. Adsorption isotherms were determined for UV absorbers and hinde red amine light stabilizers (HALS) compounds. Infrared spectral analys is revealed that chemical interactions at the pigment surface are resp onsible for the observed effects. In some cases the chemical surface i nteractions are likely to prevent the adsorbed molecules from function ing as light stabilizers. (C) 1998 Elsevier Science S.A. All rights re served.
