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 Y. Ananoria, Jullifranz M. Cagulangan, Ronelyn Grace P. Jalique, Xela Patrice B.
