Anjeka 6161 polymeric dispersant universal for organic,inorganic and carbon black with high performance BYK161

GENERAL DESCRIPTION

Anjeka-6161 is a wetting and dispersing agent used in solvent-based automotive coatings, industrial coatings, and pigment concentrates. It is particularly suitable for stabilizing high-pigment black and organic pigments, especially in two-component polyurethane and baking systems, significantly reducing the viscosity of abrasives.

PRODUCT DATA

Chemical composition: Modified polyurethane copolymer solution with pigment affinity groups.

Typical physicochemical data:
The data presented on this data sheet are merely typical values and do not constitute technical specifications for the product.

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

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:

This additive deflocculates pigments and maintains their stability through steric hindrance. Anjeka-6161 imparts the same charge to pigment particles. The resulting repulsive force and stabilizing effect of steric hindrance effectively prevent potential co-flocculation, ensuring that multi-pigment systems do not exhibit floating colors or mottling. Consequently, it enhances the gloss, color intensity, transparency, and hiding power of the coating, while also reducing grinding 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.
