Abstract

The demand of bio-based coating has been greatly increased in order to solve the environmental issues. Petroleum-based coating is expensive, hard to recycle and all the sources come from non-renewable fossil fuel. Therefore, solution needed to overcome the problem. This study was carried to synthesize ESO to produce AESO film coating. The acrylation of epoxidized soybean oil (AESO) was successfully synthesized by introducing acrylic acid, which is an unsaturated monomer into oxirane groups of the epoxidized oil (ESO). Then, AESO has been reacted with trimethylolpropane triacrylate as monomer and 3-(Triethoxysilyl)-propylamine as the curing agent to produce AESO film with varying formulation of TMPTA: amine were 70:30, 50:50 and 30:70 respectively. The oxirane oxygen content, viscosity, FTIR and acid value were obtained to know the amount of unsaturation in the synthesized product. Based on the successfulness of esterification process, FTIR result showed the hydroxyl group that exists in the AESO structure at peak 3618 cm-1. In addition, the hydroxyl group presence in the AESO film for sample ratio with 30:70 at peak 3459.6 cm-1. The viscosity of AESO was found within desirable range and higher compared to ESO which were 835.96 cP and 329.62 cP. Moreover, the result revealed that AESO has lower VOC than AESO film which was 4%. In the pencil hardness result, AESO film with ratio 30monomer:70curing agent had high scratching resistance with pencil grade 2H and indicates that the film had better properties than the others. In overall, AESO is suitable to replace petroleum-based film and used as vegetable oil-based film.
