In order to improve oil and water repellency, amino-terminated poly(dimethylsiloxane)s were blended in an epoxy resin. It was hypothesized that the low surface energy poly(dimethylsiloxane) segment will absorb and orient to the exterior of the resin to make a thin surface film. Results from an ESCA investigation showed that both the amount of Si2p and Ols in the modified resin surface increased with an increase in the modifier content, and reached 0.5. Both advancing and receding contact angles for an aluminium plate coated with modified resin dipping into and out of water and dimethylphthalate increased by the addition of these modifiers. The peel strength of a pressure-sensitive adhesive affixed to the modified epoxy resin decreased dramatically.
