Thinner Ferrochrome Lignosulfonate



FCLS - Ferrochrome Lignosulfonate is a multi-purpose deflocculant, gel-strength reducer, temperature stabilizer, inhibitor and filtration-control additive for use in all water-base systems.


Application & Features
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


FCLS has superior deflocculating capabilities, even in the presence of contaminants and elevated temperatures. It is effective at temperature in excess of 150C.


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