Zusammenfassung: | Thickener for aqueous systems comprises a mixture of (a) a water-soluble or -dispersible thickener with urethane groups; (b) a non-ionic aromatic or alkyl-aromatic emulsifier; (c) at least one compound obtained by reaction of 2-4C alkoxide with 6-22C aliphatic compounds containing active hydrogen atoms; and optionally (d) other auxiliary substances. N.B. 'Alkoxide' is used to mean alkylene oxide. |
