DISPERBYK®-164
DISPERBYK®-164 is a high molecular weight wetting and dispersing additive for solvent-borne systems and pigment concentrates. Solutions of high molecular weight block copolymers with pigment affinic groups. DISPERBYK® 164 is used in many formulations. For new developments, however, the additive DISPERBYK® 2164 (see Data Sheet W235) should be preferred. DISPERBYK® 164 has a molecular weight similar to that of DISPERBYK® 163, but is less polar and its solids content is higher. It is used in pigment concentrates and general industrial coatings. DISPERBYK® 164 does not contain aromatics.

ANTI-TERRA®-203
ANTI-TERRA®-203 is a solution of an alkylammonium salt of a polycarboxylic acid. This product is suitable for medium to low polar solvent-borne and solvent-free coating systems. It causes an increase in thixotropy. In highly filled systems, the sagging tendency is reduced; in addition, no negative influence on the water sensitivity of the paint film has been observed. When formulated into anti-corrosion primers, the protective properties are enhanced in many instances.
ANTI-TERRA®-204
ANTI-TERRA®-204 is a solution of a polycarboxylic acid salt of polyamine amides. In comparison to ANTI-TERRA-203, ANTI-TERRA-204 can additionally be used in non-polar systems and is compatible with white spirits. The lower the polarity the more the thixotropy is increased. The preferred binders are long, medium and short oil alkyds, PVC-copolymers, chlorinated rubber and epoxy. Even in "low-filled“ systems, the sagging tendency is reduced; in addition, no negative influence on the water sensitivity of the paint film has been observed. When formulated into anticorrosion primers, the protective properties are enhanced in many instances.
ANTI-TERRA®-205
ANTI-TERRA®-205 is a high molecular weight wetting and dispersing additives for solvent-borne systems. Solution of a polycarboxylic acid salt of polyamine amides.
ANTI-TERRA®-250
ANTI-TERRA®-250 is a solution of an alkylolammonium salt of a high molecular weight acidic polymer. It is used in aqueous systems and provides an increase in thixotropy and prevents hard settling of pigments. Due to controlled flocculation mechanism, the use of ANTI-TERRA-250 may lead to a minor gloss reduction.
