1.Overview

nn--CoatCoat isa hybrid coating synthesized of inorganic componentsasmain component an

d organic components as sub-component with molecular unit reaction. It hasboth inorganic propertiessuch as fire resistance,high hardness,abrasion resistance,acid resistance and organic properties such as water resistance, alkali resistance, flexibility, toughness andshock resistance.Additionally, it is the eco-friendly product which contains limited hazardousorganic solvent.
