Product #17045

Polythin is a chrome-free, highly soluble, highly anionic drilling fluid deflocculant and fluid conditioner. It works particularly well in high solids water-based muds, where temperatures exceed 200°C. It adsorbs onto the surface of clay platelets preventing the flocculation of bentonite in the presence of high temperature, contamination by salt (up to 50,000 ppm) and CO2.

Polythin will also help to augment fluid loss additives where high temperature and severe contamination is a problem. Concentration ranges from 1.4-11.5 kg/m³ depending upon the degree of contamination.
