Production of Acrylated Resin from Palm Oil and Jatropha Oil

Full-text: UV-curable coating is a green technology which has been rapidly commercialised in many applications and its demand has been rising due to global concerns over environmental protection issues. The technology has been considered environmental friendly as its eliminates the emission of volatile organic compounds with short time curing. The vegetable oils such as palm oil, jatropha oil, soybean, sun flower, linseed, castor oil have been employed for the preparation of acrylate resin to impart flexibility, hardness and chemical resistance. The use of renewable resources combined with environmentally UV-curable technology provides a green solution to the stricter regulations in the coating industry. This paper presents comparison product of epoxidized palm oil acrylate (EPOLA) and epoxidized Jatropha oil acrylate (EJOLA). The reaction was confirmed by several analytical data for example, oxirane oxygen content (OOC), acid value (AV) and IR spectrophotometer method. The acid value of the resin was determined using ASTM D0974 whereas the OOC content was analysed using AOCS Tentative Method Cd-957. The kinetics of the acrylation reaction were monitored throughout the AV and OOC of the reaction mixture. The AV and OOC decreases during the acrylation process and remain constant suggested that ring opening reaction was successfully completed. The obtained of epoxy acrylate was investigated by FTIR which reveals that acrylates resin was successfully synthesized with the presence of acrylate peaks at the absorption of 1632 and 810 cm^-1 respectively and also the absence of oxirane at the absorption peak at 834 cm^-1. The properties of the cured films were investigated by using pendulum hardness tester and gel content analysis. (author)
