KR-707 High-efficiency Pretreatment Filming Agent 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. KR-707 High-efficiency Pretreatment Filming Agent has the advantages of quick filming, film homogeneization, chemical stable and low corrosion ratio. KR-707 High-efficiency Pretreatment Filming Agent can be used as pretreatment filming agent for equipment and pipeline of new system or after heavy repair.KR-707 High-efficiency Pretreatment Filming Agent is not affected by copper and ferric ions in water system.
