Tannathin

TANNATHIN* lignite is a naturally occurring material that reduces fluid loss and deflocculates water-based drilling fluids. A partially soluble additive, it provides thin, low-permeability filtercakes. It is an excellent emulsifier for oil-in-water emulsions and secondary deflocculant as well as is especially effective in high-temperature applications. It performs exceptionally well in dispersed systems as a synergistic additive with lignosulfonates.
