Several UV-curable formulations containing epoxydiacrylate (EB-600) oligomer with a tri-functional monomer, trimethylol propane triacrylate (TMPTA), and photoinitiator Irgcure-369 were developed to improve the surface of Partex. Filler or extender CaCO3 was incorporated into the solution. Thin polymer films were prepared on glass plate with these formulated solutions and finally applied on polished Partex surface, and both were cured under UV-radiation. The properties of UV-cured thin films mere studied as a function of CaCO(3)concentration. Pendulum hardness and gel content were found to decrease on glass plate with the increase of CaCO3 concentration. Pendulum hardness, scratch hardness, and abrasion resistance of the cured Partex were found to be higher with the increase of CaCO3 content up to 4%. Thus, the formulation containing 4% CaCO3 showed the best performance over all formulations containing CaCO3.
