Special Features and Benefits:-
The additive derives its benefits from the systematic, controlled flocculation of pigments. This also prevents sagging and keeps the pigments from settling as well as flooding and floating. ANTI-TERRA-203 is suitable for medium-polar to low-polar solvent-borne and solvent-free coating systems and significantly increases thixotropy. It can often improve anticorrosive properties when used in protective coating primers. ANTI-TERRA-204 is a very similar product, which is also suitable for non-polar systems.

Recommended Levels -
Amount of additive (as supplied) based upon pigment:
- Inorganic pigments: 1-2%
- Titanium dioxide/Fillers: 0.5-1%
- Bentonites: 30-50%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing - Instructions For optimum performance, the additive must be incorporated into the millbase before addition of pigments. The following suggested formulation can be used to gel bentonites:
- 85-87 parts (by weight) solvent
- 10 parts (by weight) betonites
- 5-3 parts (by weight) additive
The solvent must either be an aromatic or white spirit with aromatics. If the gelling effect is not sufficient, polar solvents may be added to increase it.
Special Note -
Discolorations may occur in coatings based on cellulose nitrate, chlorinated rubber, and PVC copolymers. Silicate coatings have a shortened pot life. High levels may affect pot life and curing in epoxy systems. The additive’s high amine value can lead to increased viscosity in the epoxy resin.
