(Super dispersible organoclay for intermediate to high polarity solvent and liquid system
inorganic rheological additive)

The super dispersibility of Disper A81-7C rheological additive greatly simplifies the
formulation and manufacture of paints, adhesives and sealants containing moderate to
high polarity solvents, such as ketones, esters, glycol ethers and ether esters and
alcohols.
The use of Disper A81-7C offers the manufacturer an opportunity to increase productivity,
cut energy and material costs, as well as simplifying the manufacture and post correction
processes - all while maintaining the high products quality obtained with conventional
organoclay rheological additives.

Characteristics:
Easy to use.
No need to pre-gel.
No need for polar activator.
Consistent development of rheology, improving batch to batch production consistency.
Can be used to post correct.
Improves manufacturing efficiency.
High efficiency and cost effective

Physical properties:
Composition: Organic derivative of a montmorillonite clay
Color: Very light cream
Form: Finely divided powder
Particle Size (dispersed): Less than 1 micron
Fineness, through No. 200 sieve: >95%
Moisture: <4%

Applications:
DISPER A81-7C is an efficient replacement for polyamide wax and fumed silica in lower
package viscosity but requiring better sagging resistance for coating containing moderate
to highly polar solvents (ketones, esters, ether esters and alcohols), this includes polar
systems containing some aromatic solvents.

DISPER A81-7C may be used in:
Industrial coatings, wood coatings, container coatings, marine paints, anticorrosive
coatings, adhesives and sealants.

Recommended dosage:
The dosage of DISPER A81-7C to be used in a specific system depends on the degree of
thickening, sag control and pigment setting desired.
Use dosage is typically 0.3-2.0% by weight of the entire formula.
When formulating with DISPER A81-7C, a good starting point is a replacement of the
currently used organoclay or fumed silica at an equal weight, then optimizing. Less
DISPER A81-7C may be required because the full inherent efficiency can be obtained,
even under lower shear, plant conditions.
In many systems, at higher thickener concentration levels, DISPER A81-7C is more
efficient than traditional organoclay or fumed silica due to its easy to use.
Incorporation:
The easy and dependable dispersibility of DISPER A81-7C permits its additive at any point
in the manufacturing process. This rheological additive can be incorporated in the
dispersion phase under high shear and in the letdown tank under lower shear. Neither a
polar activator or a pre-gel is required.

Using the grind:
DISPER A81-7C may be incorporated anywhere during or after the pigment grind. Prewetting
or pre-dispersion is not necessary. Minimum activation temperature is not required.

Packing & storage:
Net weight 25KG, storage time 4 years in dry and cool place.
