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