Chrome-Free Lignosulphonate

GCS LIGNOFREE

Premium chrome-free lignosulphonate for improved rheology and fluid loss control.

Product Overview

GCS LignoFree is a high-performance chrome-free lignosulphonate designed as a deflocculant for water-based drilling fluid systems. It effectively disperses clay particles and controls flocculation, stabilizing fluid rheology and maintaining consistent viscosity and gel strength. It also reduces fluid loss by promoting the formation of a thin, durable filter cake, improving overall wellbore stability.
