Article's abstract:

The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured films containing Isobornyl acrylate IBOA are claimed to have good flexibility, even though to obtain higher hardness and Tg, higher functionality such as dipentaerythritol pentaacrylate DIPEPA and dipentaerythritol hexaacrylate DPHAis needed. The Tg of the acrylate formulations increased with increasing functionality of monomer and the similar trends can be adopted for the hardness.
