摘要：
A novel pourable organophilic clay polyamide composition useful as a rheological additive for organic fluid system comprising
a) from about 5 to 15 weight percent of an organophilicly modified smectite-type clay,
b) from about 25 to about 35 weight percent of one or more rheologically active polyamides and
c) from about 40 to 60 weight percent of one or more organic solvents preferably selected from the group consisting of n-propanol, toluene and mineral spirits.
The organophilic clay polyamide composition is used in non-aqueous fluid systems such as paints, inks, and coatings to provide improved rheological properties to the system.
