摘要：

The UV light behavior crossing a thick scattering and absorbing paint film has been modelled by a four-flux radiative transfer theory. For all that, the scattering characteristics of the coating as well as the calculation of the UV intensity decay through the coating thickness were measured versus TiO2 pigment concentration. Thanks to these results, the conversion profiles in the coating thickness were obtained by numerical modeling and the influence of TiO2 pigment concentration on these conversion profiles was discussed.
