The main function of a protective coating is to isolate structural/component reactive elements from environmental corrosives or abrasives. The fact that protective coatings occupy only a very small fraction of the total volume of a system is quite telling of the heavy requirements imposed on these materials. A coating must provide to a substrate a continuous barrier and any imperfection can become the focal point for degradation and corrosion of the substrate.

Abrasive blasting and spray painting are painting techniques where a device sprays a coating (paint, ink, varnish, etc.) through the air onto a surface. The most common types employ compressed gas—usually air—to atomize and direct the paint particles. Spray guns evolved from airbrushes, and the two are usually distinguished by their size and the size of the spray pattern they produce. Airbrushes are hand-held and used instead of a brush for detailed work such as photo retouching, painting nails or fine art. Air gun spraying uses equipment that is generally larger. Coating materials covers but not limited to below: 3 coat epoxy Ceramic-composite coating has been proven with its track record of providing excellent corrosion and abrasive or erosion resistance as compared to traditional polymer paint. The metallic or other functional substance added to the coating to further enhance its performance in high temperature and high wear environment. Again, its cold application is avoiding any substrate metal properties change which favours by plant operators and is useful application during shut down maintenance.
