A type of coating lining method. The Ziktect VE method is a vinyl ester resin coating lining method that does not require the impregnation and degassing process of glass mats found in conventional FRP corrosion protection methods. The vinyl ester resin, which is blended with special glass short fiber reinforcement materials, can form a corrosion-resistant coating layer using common painting tools such as rollers, trowels, and brushes. The formed corrosion-resistant coating layer excels not only in sulfuric acid resistance and alkali resistance required in sewage environments but also in chemical resistance. This method can meet quality standards A to D for coating lining methods used in sewage systems.
