assessment mechanical properties of epoxy clay nanocomposite coatings

some new multipurpose additives for solvent based epoxy coatings were synthesized. the additives were characterized by ftir spectrometry and x-ray diffraction (xrd). the additives synthesized by cationic exchange process of clay (montmorillonite) and some special protonated polyetheramines were used to develop some new epoxy systems. the introduction of new additives in epoxy systems resulted in improving mechanical properties (adhesion, persoz hardness, elasticity of coating film), durability, gloss resistance and water resistance.
