摘要

A novel organophilic clay gellant comprising the reaction product of: (a) a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of natural clay without impurities; (b) a first organic cation in an amount of from about 75% to about 150% of the cation exchange capacity of the smectite-type clay; (c) a second organic cation provided by a polyalkoxylated quaternary ammonium sa and (d) one or more organic anion(s) that is capable of reacting with said first and second organic cations, to form an organic cation-organic anion complex with said smectite-type clay. The organophilic clay gellant is used in a non-aqueous fluid system such as paints, inks, and coatings to provide improved rheological properties.
