Chrome-Free Lignosulphonate

SOL LignoFree

Dispersant

SOL 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.

  • Effective deflocculant for improved rheology control
  • Enhances dispersion of clay particles
  • Reduces fluid loss with thin filter cake formation
  • Maintains stable viscosity and gel strength
  • Compatible with various water-based mud systems
  • Performs reliably in high-temperature conditions
  • Works with polymers, starches, and shale inhibitors
  • Water-based drilling mud systems (freshwater, seawater, saltwater)
  • Used as a deflocculant and fluid loss control additive
  • Dispersed and non-dispersed mud systems
  • High-temperature drilling environments
  • Compatible with polymer and bentonite systems
