Anionic 1 :
(adj.) Drilling Fluids. Related to negatively charged ions. Clay surfaces, groups on polymer chains, colloids and other materials have distinct, negatively charged areas or ions. Anionic characteristics affect performance of additives and contaminants in drilling fluids, especially water muds, in which clays and polymers are used extensively. Ant: Cationic.
