Abstract
The demand for bio-based coating has increased greatly in order to solve the environmental issues. Thus, this research aims to synthesize AESO through acrylation process by introducing acrylic acid, which is an unsaturated monomer, into oxirane groups of ESO. Then, AESO reacted with trimethylolpropane triacrylate as a monomer and 3-(triethoxysilyl)-propylamine as the curing agent to produce AESO film with varying formulation of TMPTA:amine in the ratio 70:30, 50:50 and 30:70, respectively. The viscosity, FTIR, VOC and pencil hardness tests were conducted. The viscosity of AESO was found within the desirable range and was higher compared to ESO. Based on the successfulness of esterification process, FTIR revealed the appearance of hydroxyl group in AESO structure at peak 3618 cm−1. In addition, AESO film with sample ratio 30:70 showed the appearance of hydroxyl group at peak 3459.6 cm−1. Moreover, the result revealed that AESO has lower VOC than AESO film which was 4%. AESO film with ratio 30:70 agent had high scratching resistance with pencil grade 2H and indicated that the film had better properties than the others. Overall, AESO is suitable to replace petroleum-based film, and it has to be used as biofilm.
