SDF - Causticised Lignite

Causticized Lignite is a causticised dispersant specially formulated and chemically modified organic compound of lignite that posseses improved dispersing ability over untreated lignite. Causticized Lignite is a partially soluble additive that provides thin, low-permeability filter cakes accompanied by low fluid loss. It controls rheology and reduces fluid loss, extends temperature limits, emulsifies oil, reduces flocculation and stabilizes water base drilling fluids In solution, it has an alkaline pH, therefore it does not require large caustic additions to maintain a stable pH.
