Bentonite
is one of the two naturally occurring minerals of
montmorillonite group with decolorizing and absorbing
properties, the other minerals of this group being fuller’s
earth. On exposure, almost all Bentonite assume a slightly
darker shade due to absorption of moisture. Two types of
Bentonite viz., swelling and non-swelling types are commonly
known in trade. Sodium Bentonite is of swelling type while
calcium Bentonite is non-swelling. Bentonite is believed to have
been formed by the alteration of volcanic ash deposits, mostly
of Upper Cretaceous Age. The commercial importance of Bentonite
depends more on its physico-chemical properties such as Base
Exchange capacity, thixotropy, settling time, swelling power, pH
value, etc. then on chemical composition. Treated Bentonite has
been used in palletizing of iron ore fines, in ceramic nuclear
fuels and ceramic moderators.
Sodium and calcium Bentonite are distinctly characterized by
high ration of their dominant exchangeable base. Intermediate
type Bentonite may have either sodium or calcium base dominant
but in low or nearly equal ratios-mixed Bentonite may exhibit
low, high or equal ration of sodium and calcium iron but contain
a higher percentage of non-clay material and/or other clay
minerals. Plasticity and bonding strength of all bentonite and
dilatency (swelling capacity) viscosity (resistance to flow),
thixotropy (getting strength) of sodium bentonite are all due to
colloidal nature of bentonite. Sodium bentonite (high
swelling-high gel) are strongly hydroscopic exhibiting a great
affinity for water.
Non-swelling bentonite (sub-bentonite meta-bentonite) are
calcium bentonite. Calcium bentonite is more common than sodium
bentonite because calcium is higher in the replacement series.

SPECIFICATION OF BENTONE 500
BENTONE 500
additive is an easy to disperse orgtanoclay rheological
additive that is useful in offset and letterpress printing
inks which are produced using only moderate levels of shear.
This rheological additive requires neither the shear nor the
chemical activation needed when using conventional
organoclays. It is an efficient replacement for fumed silica
and other gelling agents. And BENTONE 500 additive is
most effective in printing inks containing aliphatic,
aromatic or naphthenic oils and solvents it is not normally
suitable for systems containing high polarity, oxygenated
solvent such as esters, ketones and alcohols.
