| Abstract: | Several UV-curable formulations containing urethane acrylate (M-1200) oligomer with a trifunctional monomer, trimethylol propane triacrylate (TMPTA), and photoinitiator Irgcure-369 were developed to improve the surface of plywood. Thin polymer films were prepared on glass plate with these formulated solutions and finally applied on polished plywood surface to modify the surface, and both were cured under UV-radiation. The properties of UV-cured thin films were studied as a function of UV-radiation intensities. Pendulum hardness (PH) and gel content were found to increase with the increase of TMPTA concentration up to a certain level and with further increase of monomer concentration the physical properties were decreased. The polymer-coated surface yielded enhanced physico-mechanical properties compared to that of unmodified surface. |
