Tóm tắt: | The purpose of this paper is to evaluate the photoprotective efficiency of organic UV absorber Tinuvin 384 (T384) on the photocurable acrylate urethane coating under the accelerated weathering condition. The coatings without and with 2 wt.% T384 were examined by UV/CON accelerated weathering testing device. The aging of the coatings was assessed by IR and FE-SEM analysis as well as the measurement of mechanical and weight loss. The obtained results showed that due to the photoprotection of T384, the urethane acrylate coating was stable under the effect of accelerated weathering factors. After 48 cycles of aging, the CH and CNH groups, the abrasion resistance and the weight of the paint films containing 2 wt.% T384 were slightly decreased. Its surface was damaged just a little, while that of the coating without T384 was severely degraded. |
