This paper describes the encapsulation procedure of an alkyd resin derived from palm oil. The palm oil-based alkyd having carboxylic and hydroxyl moieties can be tailor-made to suit the intended application. Microencapsulation process was done using poly(urea-formaldehyde) (PUF) resin as shell material. The microcapsules obtained were free-flowing, with 80 -90% core encapsulated, and are intended to be used in self-healing material development. The functional groups of alkyd and shell material were observed using ATR-FTIR. DSC analysis shows melting peaks and glass transition of PUF and alkyd in the microcapsules. TGA analysis indicated that the shell of the microcapsules was thermally stable up to 250 °C. FESEM examination showed that the microcapsules had rough outer surface.
