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.

摘要:
A rheological additive especially for liquid organic systems containing a castor-oil derivative with hydroxyl values below that appearing in nature. The additive may also contain clays and other extenders. The preferred derivative is castor wax. The additive largely eliminates the long term problem of seeding exhibited by paints and coatings using castor-oil derived additives while simultaneously providing improved dispersability and viscosity modifying qualities.

摘要:
Improved organophilic clay gellants for highly viscous systems such as asphalt and creosote can be prepared by a process wherein the smectite-type clay is gently dried and/or subjected to minimum or no grinding. The organophilic clay agent may be used to thicken a variety of organic compositions including pitch and heavy resins. In a preferred aspect, the organophilic clay gellant can be directly added to asphalt systems in order to efficiently and effectively modify the viscosity thereof without the use of either a polar activator as a dispersion agent or a preactivation agent.
