Anti-Terra-203 is a controlled flocculating wetting and dispersing additive for solvent-borne, medium-polar to low-polar thick layer systems and primers. It prevents the settling of fillers and inorganic pigments and aids in the gelling of bentonites. Key features include flooding resistance, floating resistance, high sagging resistance, and anti-settling properties. It functions as both a wetting agent and dispersant in solventborne and solventless coatings. The product is compliant with TSCA, TSCA Exempt, and DSL chemical inventories.

Features & Benefits

CASE Ingredients Features
Key Features
  • 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.

Compatibility
  • Solution of an alkylammonium salt of a polycarboxylic acid
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.

Regulatory & Compliance

Technical Details & Test Data

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.

Storage & Handling

Storage and Transportation
  • Separation or turbidity may occur at temperatures below 5 °C. Warm to 20 °C and mix well.
