Abstract

This research aims to synthesize a biobased polyurethane coating from epoxidized palm oil (EPO) and determine the effect of different silicon dioxide (SiO2) loadings on the hydrophobicity performance of the coating. In this work, EPO was firstly undergoing an acrylation reaction and followed by the addition of isophorone diisocyanate (IPDI) to form Polyurethane (PU). Improvement was made by adding SiO2 at different loadings into the palm oil-based PU to provide hydrophobic properties to the coating materials. The sample was characterized using Fourier Transform Infrared Spectroscopy (FTIR), water sliding angle test, and water absorption test. Based on the FTIR results, PU was successfully synthesized from EPO with SiO2 addition. The results also proved that the addition of SiO2 successfully improved the hydrophobicity of the coating. The higher the SiO2 content in palm oil PU, the shorter the time taken for the water to slide down the 25° angle coated glass and lower the water absorption percentage of the coating material. Based on the analysis, 3 phr SiO2 content showed the highest hydrophobicity performance, which could be applied in further research.
