Zusammenfassung: | 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. |
