Dimer Acid-RS E 80

Uniquely designed Low End Rheology Modifier (LERM) used in preparation and maintenance of oil or synthetic-base drilling fluids for invert emulsions. This oil-mud secondary emulsifier lowers the interfacial tension between oil and water, as well as boosts low-shear-rate rheology, improving barite suspension, especially when annular velocity is low or fluid density is high.
