There is hardly any technology that has attracted an immense interest in a shortest spell of a few years. Whether it is materials development, chemistry, physics or engineering sciences, there are ample examples where nano-science or technology has created sign of positive developments. Chemical Industry has played a very important role in developing not only nano-materials but also make use of them in various applications. One field where nanotechnology has created a ripple is the paint coatings. Whether it is the improvement of chemical resistance, erosion and abrasion resistance, resistance to U.V. light, anti-fouling properties, nano-modified paints have shown great potential in several industrial applications
