Anjeka6622 wetting dispersing agent for pigment concentrated pastes high-solid system BYK2155

GENERAL DESCRIPTION

Anjeka-6622 is a 100%-active, VOC-free, and solvent-free wetting and dispersing additive designed for high-performance applications. It is broadly compatible with solvent-borne, solvent-free, and high-solids systems, including industrial coatings, floor finishes, and printing inks. Its exceptional compatibility profile makes it especially recommended for manufacturing stable pigment concentrates (color pastes).

Application Information/APPLICATION GUIDELINES

Industrial Coatings

Features and Benefits:

Anjeka-6622 deflocculates and stabilizes pigments by spatial site resistance. They provide the same charge to the different pigments, thus avoiding possible co-flocculation of the different pigments. Due to the deflocculation of the additives, gloss and coloring power can be improved, the transparency of transparent pigments and the hiding power of opaque pigments can be increased, and the viscosity of the pastes can be reduced at the same time.

APPLICATION SECTORS

Due to its high-efficiency formulation, Anjeka-6622 is especially recommended for high-solids systems and floor coatings. It exhibits broad compatibility with standard resin systems, including alkyd resins, nitrocellulose, polyols, chlorinated rubber, epoxies, and polyurethanes.

Anjeka-6622 significantly reduces paste viscosity, enabling higher pigment loading and improved processing characteristics.

RECOMMENDED LEVELS

The following additions are based on the ratio of dispersant solids to pigment amount:

Inorganic pigments: 5%-10%

Titanium dioxide: 1%-3%

Organic pigments: 10%-35

Carbon black: 15%-75

The above data are empirical, the optimal amount should be determined through a series of tests.

INCORPORATION and PROCESSING INSTRUCTIOS

For best performance, the wetting and dispersing agent should be added to the abrasive. In the case of non-resin dispersions, the solvent in the mix should be premixed with the additives under stirring conditions and added before the pigments. In the case of resin dispersion, the resin mixture, solvent and additives should be well mixed before adding the pigment.
