GENERAL DESCRIPTION
Anjeka-6161 is used as a wetting and dispersing additive for solvent-borne automotive coatings, industrial coatings and pigment concentrates. It is particularly suitable for stabilizing highly pigmented 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: Light yellow liquid
Density g/cm³ (23°C): 0.90 - 1.00
Acid value (mg KOH/g): 2-10
Amine value (mg KOH/g): 1-5
Active ingredient (%): 50
Viscosity cps (25℃): 100-300
Solvent: Xylene/butyl acetate/propylene glycol methyl e ther 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 more suitable than amine-encapsulated acids.
APPLICATION GUIDELINES
Features and Benefits:
The additive unflocates and stabilizes the pigment by spatial site resistance.Anjeka-6161 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.

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 figures are empirical and the optimum dosage should be determined by a series of tests.
INCORPORATION AND PROCESSING INSTRUCTIONS
For best performance, the resin and solvent components of the abrasive should be pre-mixed, then the additives should be added slowly with constant stirring, followed by the pigments. Pigments should not be added until the additives are well mixed.
