Roclean series - phosphonates - exhibit an excellent sequestration of metal ions. These substances can be used at very low levels to control corrosion, scale and fouling growth in cool water system, oil field pipelines and boilers. The ability of phosphonates to deflocculate or disperse solid particles combinated with their hydrolytic stability makes them versatile ingridients for applications requiring efficient metal ion control such as industrial and institutional cleaners, water treatment, textile auxiliaries, metal pretreatment etc.
