Liquid Epoxy Coating

Liquid Epoxy Coating is a high-performance, protective coating for the internal and external surfaces of steel pipes. It consists of an epoxy resin and a curing agent that, when mixed, undergo a chemical reaction to form a tough, seamless, and chemically resistant barrier. It effectively isolates various corrosive media such as water, acids, alkalis, salts, and petroleum products, significantly extending the service life of pipelines and ensuring the purity of the conveyed medium. Liquid Epoxy Coating is widely use in oil & gas, water, and chemical industries.
