Article's abstract:

Create three-dimensional network of siloxane polymer in the epoxy resin is an appropriate mechanical properties .Dispersion of nanoclay in these coating was prepared by ultrasonication method. Mechanical properties of nanocomposit coatings such as abrasion, hardness and adhesion was increased by addition of nanoclay montmorillonite. Different percentages of nanoclay in coating showed that even small amounts of nanoclay increased mechanical properties . Stability and morphology of nanocomposite coating was evaluated by TEM , XRD and optical microscope .The results obtained show a stable dispersion of clay layers into the matrix and showed higher dry and wet adhesion in compare with pure epoxy –siloxane coating.
