Gel-forming organophilic layered silicate, the exchangeable cations of which are wholly or partly by a quaternary ammonium compound of the formula are replaced, wherein R, and R 2 may be the same or different and C 6 -C 30 alkyl or C 6 -C 30 alkenyl, R 3 C 1 -C 6 alkyl, R 4 C 1 -C 6 alkyl , A is the group -C 2 H 4 - or -C 3 H 6 - and n is 1 or. These organophilically modified layered silicates are used as thixotropic agents, for example pasture for paints and anti-rust primers. |
