1.Overview

n -Coat is a hybrid coating synthesized of inorganic components as main component an d organic components as sub-component with molecular unit reaction. It has both inorg anic properties such as fire resistance, high hardness, abrasion resistance, acid resistance a nd organic properties such as water resistance, alkali resistance, flexibility, toughness and shock resistance. Additionally, it is the eco-friendly product which contains limited hazard ous organic solvent. OH OH
