Abstract

Microcapsules had Urea Formaldehyde (UF) shell and linseed oil core were investigated manufacture. Synthesis UF shell of Microcapsules was experimented by emulsion polymerization and pH was only adjusted once by mixer of Resorcinol / Amoni Clorua. Content of Urea and emulsifiler Sodium Dodecyl Sulphate, pH, agitation rate were investigated. This research shows that the linseed oil (core) is disintegrated at 1,500 rpm in pH = 5.5 with 1.2% (w/w) Sodium Dodecyl Sulphate. In addition, the combination of Urea used in order to create the shell about 40% (w/w) linseed oil and Formaldehyde are suitable. The microcapsules products have the average size less 100 μm. Besides that, the content of the linseed oil in the core is about 87% (w/w)take the advantage to use in self-healing coating.
