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.
