The effect of pigment dispersion on (i) surface morphology and appearance, and (ii) the weathering durability of a TiO2 pigmented epoxy coating was investigated. The microstructure and dispersion of pigmented epoxy coatings were characterized using ultra small angle neutron scattering (USANS). Atomic force microscopy (AFM) and laser scanning confocal microscopy (LSCM) were used to characterize surface morphology of unexposed and weathered coatings. Surface optical scattering and commercial gloss measurements were carried out to study the corresponding optical properties of the coatings. Preliminary results of optical and surface morphological changes are presented and related to material properties as a function of outdoor weathering for two coatings of different dispersion states. © 2009 American Chemical Society.
