A polysiloxane diglycidyl ether was used as a comonomer of epoxy resins to obtain coatings through the ultraviolet curing technique. Notwithstanding its very low concentration (<1 wt %), the siloxane monomer caused a change in the surface properties of the films. Selective surface stratification was evidenced by X-ray photoelectron spectroscopy analysis, and an interesting surface modification was achieved without changing the bulk properties of the films or the rate of polymerization.

Abstract
A polysiloxane diglycidyl ether was used as a comonomer of epoxy resins to obtain coatings through the ultraviolet curing technique. Notwithstanding its very low concentration (<1 wt %), the siloxane monomer caused a change in the surface properties of the films. Selective surface stratification was evidenced by X-ray photoelectron spectroscopy analysis, and an interesting surface modification was achieved without changing the bulk properties of the films or the rate of polymerization.File in questo prodotto:
