Abstract:
In this work, synthesis and characterization of siliconized epoxy resin were studied. Polydimethylsiloxane (PDMS) with different molecular weights were reacted with an epoxy resin through a fusion process. The structure of the modified epoxies were studied by means of FTIR and EEW measurement. An amine based component was used as curing agent. The morphology of the cured films was studied by using transition optical microscopy (TOM) and scanning electron microscopy (SEM) instruments. With incorporating PDMS into epoxy structure a two-phase microstructure was obtained. The observations illustrate that the continuous phase is enriched by cured epoxy resin and the dispersed phase composed by silicone resin. It can be concluded that the efficiency of the reaction is affected by silicone molecular weight and amount.
