BYK®-323
BYK®-323 is an aralkyl modified polymethylalkylsiloxane. This product acts in a defoaming fashion (i.e., no or only slight foam stabilization), depending on the polarity of the paint system. It is heat resistant up to 250°C and does not decrease intercoat adhesion when overcoated. In wood and furniture coatings, BYK-323 is used to orient the flatting agent in flat topcoats and in multi-coat systems. Even in difficult to flat high-solids polyurethane, acid curing and unsaturated polyester coatings, the use of BYK-323 does not lead to shining up. In addition, optimal orientation of the flatting agent is achieved. In flow coat systems, BYK-323 provides a stable curtain. In industrial coatings, BYK-323 supports the orientation of flatting agents and aluminium flakes in metallics.

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.
