BENTONE® 34
Rheological Additive for Low to Intermediate Polarity Organic Systems
GENERAL INFORMATION KEY PROPERTIES
BENTONE 34 is an organic derivative of a bentonite Increases viscosity
clay. This rheological additive is designed for low to Provides thixotropy
intermediate polarity organic systems.

Density 1.7 g/cm3
Moisture max. 3% INCORPORATION
These are typical properties not to be used for specification Incorporation of BENTONE 34 in organic systems
purposes. (e.g. paints) requires high-shear dispersion
equipment and a chemical activator.
APPLICATIONS Two basic incorporation methods can be used:
Adhesives 1. Addition of BENTONE 34 as a dry powder for
Anti-corrosive paints in-situ dispersion and activation
Automotive finishes The BENTONE 34 powder is added directly to
the resin/solvent blend and is thoroughly mixed
Bituminous compositions for 10 minutes. A chemical activator (see below)
Buffing compounds should be added next and mixed for 10 minutes.
Coil coating systems The pigments and fillers are then added and
dispersed with high shear for at least 15 minutes.
Dip coatings
2. Addition of BENTONE 34 as pregel of 5%–10%
Finishes for household appliances by weight
Greases The solvent is charged to the mixing tank.
High-build systems BENTONE 34 powder is added and dispersed
under high shear. A chemical activator can then
Industrial finishes be introduced to optimize gelation (see below).
Interior and exterior house paints including For incorporation in the full formulation the pregel
do-it-yourself paints is added to the resin/solvent mixture with stirring.
Knifing fillers Pigments and fillers are then incorporated and
dispersed under high shear.
Mould release agents

LEVELS OF USE
The level depends on the system in which
BENTONE 34 is to be used. For house paints and
industrial paints typical levels are between 0.2 and
Enhanced Performance Through Applied Innovation
0.5 % (dry).
BENTONE 34 based on total system weight. For
primers slightly higher quantities are required (0.5 -
1 % dry BENTONE 34).
In aqueous systems between 0.2 and 0.3 %
BENTONE 34 (dry) are used
