Ferrochrome Lignosulfonate (FCLS)

RXSOL FCLS is an excellent all-purpose deflocculant and fluid-loss-control agent. It is effective for viscosity control and fluid loss reduction in all water-base mud systems, including freshwater, brackish water, seawater, salt, lime, gyp and potassium systems.

RXSOL FCLS  has superior deflocculating capabilities, even in the presence of contaminants and elevated temperatures. It is effective at temperature in excess of 150℃ (302℉).

Due to the product's low pH, treatments require additional caustic soda or an alternative alkaline material, to maintain a consistent pH.RXSOL FCLS  is most effective in mud systems with an alkaline pH in the range of 9 to 11.
