The main aim in this work was to prepare resol type phenolic resin nanocomposite blends and was to investigate surface coating properties of their films. Firstly, phenolic resin nanocomposite blends were prepared by blending of bentonite (B) or silica (S) at different weight ratio (1, 2, 5 and 10 %) with resol resin. This nanocomposite blends were characterized by X-ray diffraction (XRD) and SEM analysis. Thermal properties of these nanocomposite blends were also investigated using of thermogravimetric analysis (TGA) technique. In order to investigate the usage of the nanocomposite blends as surface coatings materials, films were prepared from these products and applied standard test methods. The results showed that these products are thermally stable materials and all films are glossy or semiglossy and have excellent drying, adhesion properties.
