Nano Coating Nano coating is a new type of thermal insulation material. It is made of a variety of inorganic fibers, nano-silica aerogel fillers and other materials as the main body, water as the dispersion medium, adding special adhesive, after fiber loosening, stirring and made of sticky slurry. It can be directly covered with spraying or coating on the surface of the metal or other materials to be protected, and the protective layer with high heat preservation effect can be formed by baking and curing at room temperature or low temperature. The product has the characteristics of low thermal conductivity, high bond strength, short drying time, low shrinkage, and not easy to crack after drying. It is the best choice for equipment, storage tank, special shape and complex condition insulation.
