ANJEKA-6500 recommended for stabilizing inorganic pigments
GENERAL DESCRIPTION
Anjeka-6500 is a copolymer featuring acidic functional groups. It is primarily employed as a dispersant in solvent-based coatings and inks with medium to high polarity resins, especially for effectively dispersing titanium dioxide and other inorganic pigments.
PRODUCT DATA
Chemical composition: Copolymer with acidic groups.
Typical physical and chemical data:
(The values listed are typical and not intended as product specifications.)
Appearance: Light yellow fluid
Acid value (mg KOH/g): 100-200
Density g/cm³ (23℃): 1.00-1.20
Viscosity cps (25℃): 100-800
Active ingredient (%): 100
STORAGE and TRANSPORT
Stir thoroughly before each use. At temperatures below 15℃, the product may separate or become cloudy; in such cases, warm to 30℃-40℃ and mix well to restore uniformity.
Recommended storage duration should not exceed 12 months.
SPECIAL NOTES
Due to the product's elevated acid value, it has the potential to accelerate cross-linking reactions in baking paint systems that are acid-catalyzed. It is advised to monitor for any viscosity increase during storage of the formulated paint.
APPLICATION GUIDELINES
Coating industry and printing inks
Properties and Advantages:
This additive deflocculates and stabilizes pigments through steric hindrance. The resulting smaller deflocculated pigment particles help eliminate color floating and blooming in multi-pigment systems, thereby enhancing gloss, color strength, transparency, and opacity of the final coating. It also lowers viscosity, which improves flow properties and allows higher pigment loading. In electrostatic high-speed spinning applications involving inorganic pigments, it markedly reduces haze.
APPLICATION SECTORS
Recommended for stabilizing inorganic pigments—particularly titanium dioxide—in solvent-borne, solvent-free coatings, and printing inks. Its anionic nature makes it especially suitable for acid-catalyzed systems, such as those used in coil coatings.
RECOMMENDED LEVELS
Dosage (based on the purchased additive form) relative to pigment weight:
Titanium dioxide: 1%-2%
Inorganic pigments: 3%-6%
These are guideline values derived from experience; optimal dosage must be confirmed through laboratory testing.
INCORPORATION AND PROCESSING INSTRUCTIONS
For optimal results, incorporate the additive into the millbase/grind mixture prior to adding the pigments.
