Photopolymerized Talisay (Terminalia catappa) Seed Oil Bio-based Coating: Hardness and Thermal Study
Keywords:Bio-based, coating, photopolymerization, hardness, TGA
The effects of formulation factors on the pencil hardness and thermal degradation properties of a bio-based coating derived from Talisay (Terminalia catappa) seed oil extract were studied. 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℃.
