UV-LED as a New Emerging Tool for Curable Polyurethane Acrylate Hydrophobic Coating.

The elimination of mercury, low energy consumption, and low heat make the ultraviolet light-emitting diode (UV-LED) system emerge as a promising alternative to conventional UV-mercury radiation coating. Hence, a series of hydrophobic coatings based on urethane acrylate oligomer and fluorinated monomer via UV-LED photopolymerisation was designed in this paper. The presence of fluorine component at 1160 cm, 1235 cm, and 1296 cm was confirmed by Fourier Transform Infra-Red spectroscopy.
