ANJEKA-6882
GENERAL DESCRIPTION
Anjeka-6882 is a wetting and dispersing additive for solvent-borne coating systems
and resin-containing pigment concentrates with a wide range of compatibility. It is
especially compatible with thermoplastic acrylic (TPA) and nitrocellulose systems.

Application Guidelines:
Features and Benefits.
Anjeka-6882 is an additive that unflocculates pigments by spatial resistance
stabilization, which also causes the pigment particles to have a charge of the same
nature. The resulting repulsive effect and spatial stabilization prevents pigment
regrind, thus eliminating blooming in systems containing multiple pigments. Due to
the small particle size of the deflocculated pigments, high gloss and enhanced color
strength can be achieved. In addition, the transparency of transparent pigments and
the hiding power of opaque pigments can be improved. Due to the reduced viscosity,
the leveling properties are improved and the amount of pigment added can be
increased.
Application Sectors:
Anjeka-6882 has excellent compatibility with all conventional solvent-borne
coating substrates, especially with thermoplastic acrylic (TPA) and nitrocellulose
systems. This additive is particularly recommended for the production of pigment
concentrates containing resins. Due to its ability to reduce the viscosity of the
abrasive significantly, it increases the pigment content of the color paste. The
additive can also be used for co-milling pigments in solvent-borne coatings.
Recommended Levels:
The amount of additive (in purchased form) is based on the pigment:
Inorganic pigments: 10%-15
Titanium dioxide: 3%-5%
Organic pigments: 30%-60
Carbon black: 60%-140
The above data are empirical and the optimum dosage should be determined
through a series of tests.
INCORPORATION AND PROCESSING INSTRUCTIONS
In order to achieve optimum performance, the additives must be added to the
abrasive before the pigments. Pre-mix the resin and solvent components of the mix
and add the additives slowly with stirring. Only after the additives have been
completely dispersed can the pigments be added.

25 kg iron drum with inner coating
180 kg ring plastic drums
