GENERAL DESCRIPTION
Anjeka-6164 is a wetting and dispersing additive for solvent-borne automotive and industrial coatings and pigment concentrates. It is particularly suitable for stabilizing very fine carbon blacks and organic pigments, especially in two-component polyurethane and baking systems, and significantly reduces the viscosity of abrasives.
PRODUCT DATA
Chemical composition: Solution of a modified polyurethane copolymer with pigment affinity groups.
Typical Physical and Chemical Data:
The data given on this data sheet are typical values and are not product specifications.
Appearance : Yellow liquid
Acid value (mg KOH/g) : 1 - 15
Amine value (mg KOH/g): 1 - 15
Density g/cm³ (23°C): 0.90 - 1.10
Active ingredient (%) : 35
Solvent Xylene /PMA/ Butyl acetate
STORAGE and TRANSPORT
Layering or turbidity may occur at temperatures below 0°C. Heat to 20°C and mix thoroughly.
Storage time is not recommended to exceed 12 months.
SPECIAL NOTES
The surface treatment of some organic pigments may adversely affect the effectiveness of this wetting and dispersing additive. In such cases, untreated pigments of the same type may be used. When used in coil coatings, the interaction between the cationic additive and the acid catalyst must be considered. Free or epoxy-encapsulated acids are preferable to amine-encapsulated acids.
APPLICATION GUIDELINES
Industrial Coatings
Features and Benefits:
The additive unflocates and stabilizes the pigment by spatial site resistance.Anjeka-6164 provides the same charge to the pigment particles. The resulting repulsive and spatial stabilization prevents possible co-flocculation and prevents floating and blooming in multi-color systems. The result is an increase in gloss, color strength, transparency and hiding power, as well as a reduction in milling viscosity.

●--Special recommendation; ○--Recommendation
RECOMMENDED LEVELS
The amount of additives (in purchased form) is based on the pigment:
Titanium dioxide: 5%-6%
Inorganic pigments: 10%-15
Organic pigments: 30%-80
Carbon black: 70%-140
The above data are empirical and the optimum dosage should be determined through a series of tests.
INCORPORATION AND PROCESSING INSTRUCTIONS
For optimum performance, add the additives to the abrasive before adding the pigments. Pre-mix the resin and solvent components of the abrasive and add the additives slowly with stirring. Do not add pigments until the additives are well mixed.
