Pretreatment Filming Agent | XT-707
XT-707 is composed of a chelating agent, dispersant, pretreatment filming, and surfactant. The chelating agent can chemically adsorb ferric and calcium, forming a hard film on a metal surface. It has the advantages of quick filming, film homogenization, chemical stability, and low corrosion ratio. It can be used as a pretreatment filming agent for the new system's equipment and pipeline or after heavy repair. XT-707 is not affected by copper and ferric ions in the water system.
