APPLICATION GUIDELINES
Industrial Coatings
Features and Advantages:
The additive employs steric hindrance to facilitate pigment deflocculation and maintain stability. ANJEKA—6173 imparts the same charge to pigment particles, generating repulsion and steric hindrance that effectively prevent potential flocculation. This enhances the coating's gloss, color intensity, transparency, and coverage, while also reducing grinding viscosity.

RECOMMENDED LEVELS
Additive levels (as purchased) based on pigment:
| Titanium Dioxide: | 5%—6% |
| Inorganic Pigments: | 10%—15% |
| Organic Pigments: | 20%—80% |
| Carbon Black: | 30%—120% |
The above data are empirical levels; optimal levels should be determined through a series of experiments.
PROCESSING INSTRUCTIONS
For optimal performance, add the additive to the grinding media before introducing pigments. Pre-mix the resin and solvent components of the grinding media, then slowly add the additive under constant stirring. Do not add pigments until the additive is uniformly mixed.
