ABSTRACT:
Gel-forming organophilic layer silicate whose exchangeable cations have been wholly or partly replaced by a quaternary ammonium compound of the formula ##STR1## where R.sub.1 and R.sub.2 can be identical or different and denote C.sub.6 C.sub.30 -alkyl or C.sub.6 -C.sub.30 -alkenyl, R.sub.3 denotes C.sub.1 -C.sub.6 -alkyl, R.sub.4 denotes C.sub.1 -C.sub.6 -alkyl, A denotes the group --C.sub.2 H.sub.4 -- or --C.sub.3 H.sub.6 -- and n denotes 1 or 2. These organically modified layer silicates are used as thixotroping agents, for example for surface coatings and antirust primers.
