Features and Benefits:
Anjeka-6621 has a highly branched chemical structure and is designed for use in solvent-free
epoxies as well as other reactive systems such as two-component polyurethanes and acid
catalyzed systems. During the milling process of the pigment and filler, the polyester side chain
of the additive is compressed while the adhesion of the amine groups to the surface of the
pigment or filler is increased. The pigment affinity groups are adsorbed on the surface of the
pigmented filler, while the polyester side chains remain wrapped around the amine groups,
preventing them from reacting with the epoxy resin. The additive significantly reduces
viscosity and does not react with the resin, resulting in long term storage stability.
Anjeka-6621 wets and deflocculates pigments well. The additive is widely compatible and has
no negative effect on coating properties such as yellowing resistance, metal adhesion or

RECOMMENDED LEVELS
The following additions are based on the ratio of dispersant solids to pigment volume:
Inorganic pigments: 5%-10%
Titanium dioxide: 1%-3
Organic pigments: 20%-45
Carbon black: 20%-80
The above data are empirical, the optimal amount should be determined through a series of
tests.

INCORPORATION AND PROCESSING INSTRUCTIONS
In order to obtain the best effect, the additives should be added to the abrasive before adding
the pigment, so as to fully utilize the effect of the additives. Pre-mix the resin and solvent
components of the abrasive, then slowly add the additives with constant stirring. After the
additives are fully dispersed, then add the pigments
