摘要：
The ultraviolet curing process of polyurethane acrylate (PUA) coating was monitored by infrared spectroscopy. The properties such as pendulum hardness, flexibility and impact resistance of the coating were measured under various formulations and curing conditions. The effects of γ-methacryloxypropyltrimethoxysilane (KH570) on adhesion of adhesive were studied followed by enhanced mechanism. The results show that, increasing light intensity, reducing the amount of diluent and prolonging curing time are all beneficial to increase C=C conversion and the pendulum hardness. With increase of the photoinitiator concentration, C=C conversion increases firstly and then decreases. The flexibility and impact resistance of the coating are better with the higher proportion of polyurethane diacrylate. In addition, KH570 could enhance the coating adhesion, especially standing a period of time. It is concluded that the main mechanism is the polymerization of C=C between KH570 and PUA and the formation of hydrogen bond between the hydroxyl group of hydrolyzed KH570 and the substrate. © 2018, Editorial Board of Polymer Materials Science & Engineering.
