The bio-based coating was prepared using thiol-ene coupling via photopolymerization. Pencil hardness measurements of the film coating were performed and results show that increasing Oil/MDI ratio decreases the hardness of the film coating. Furthermore, thermogravimetric measurements show that the film coating is thermally stable up to 300℃.</p> Abhel Ananoria Jullifranz Cagulangan Ronelyn Grace Jalique Xela Patrice Pingol Copyright (c) 2022 2022-03-14 2022-03-14 5 2 1 3
