Asia-Pacific Journal of Science, Mathematics, and Engineering https://journals.msuiit.edu.ph/apjsme <p>The Asia-Pacific Journal of Science, Mathematics, and Engineering is aimed at providing a publication outlet for researchers in the Asia and Pacific regions. Papers published in the journal covers research in both basic and applied aspects in science, mathematics, and engineering. Review papers are also welcome.</p> Office of the Vice Chancellor for Research and Extension - MSU-IIT en-US Asia-Pacific Journal of Science, Mathematics, and Engineering 2244-5471 Photopolymerized Talisay (Terminalia catappa) Seed Oil Bio-based Coating: Hardness and Thermal Study https://journals.msuiit.edu.ph/apjsme/article/view/50 <p dir="ltr">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℃.</p> Abhel Ananoria Jullifranz Cagulangan Ronelyn Grace Jalique Xela Patrice Pingol Copyright (c) 2022 2022-03-14 2022-03-14 5 2 1 3
