(1) ZOW-707 is a pretreatment filming agent together with chelating agent, dispersant and surfactant. The chelating agent can chemically adsorb ferric and calcium, forming a hard film on metal surface. It has the properties of quick filming, film homogeneization, chemical stability and low corrosion rate. It can be used as pretreatment filming agent for equipments and pipelines of new or after-repair systems.
(2) ZOW-707 is not affected by copper or ferric ions in water system.
The dosage of 200~500mg/L is preferred. Pretreatment filming time for cold state is 48~72 hours, and for heat state is 24~48 hours.
Acidic. Avoid contact with eyes and skin. Once contacted, flush with water.
