Features and Benefits
This additive stabilizes the pigment through steric hindrance and causes it to deflocculate. Due to the small particle size of the flocculent pigment, it can achieve high gloss and enhance color strength. In addition, the transparency of transparent pigments and the hiding power of opaque pigments have also been improved. Due to the decrease in viscosity, the flow performance has been improved, and the pigment content can be increased.
This additive is used to produce stable resin free pigment concentrated slurry for the preparation of water-based coatings without floating/blooming.
Suggested dosage
Inorganic pigments: 20% -30%
Titanium dioxide: 10% -12%
Organic pigments: 30% -75%
Carbon black: 130% -150%
Filler: 1-3%
Addition method and processing guidance: Grinding can only be carried out in water (excluding resins, amines, and co solvents). The auxiliary agent should be mixed with water, and then the pigment can be added only after the auxiliary agent is fully and evenly dispersed.
Storage and Packaging
