Abstract
The study aims to explore the anti-staining property of fluorine-modified polyurethane-acrylic coatings (FPA) and polyurethane-acrylic coatings (PA) in simulated natural environmental (UV light, acid rain, dust). The results show that FPA coatings' anti-staining property was better than that of PA coatings at the early stage of exposing time but declines gradually. The analysis of failure mechanism was based on the results of three relevant surface properties: glossness, contact angle and sliding angle, which suggest that the failure mechanism of anti-staining property of hydrophobic FPA coatings differs from that of hydrophilic PA coatings.
