The Synergistic Effects of Sio<sub>2</sub> Nanoparticles and Organic Photostabilizers for Enhanced Weathering Resistance of Acrylic Polyurethane Coating
This study aims to evaluate the synergical effects of SiO<sub>2</sub> nanoparticles (nano-SiO<sub>2</sub>) and organic photostabilizers (Tinuvin 384 (T384) and Tinuvin 292 (T292)) on the weathering resistance of acrylic polyurethane coating. Data obtained from infrared (IR),...
