ANJEKA-6401 Anti-Floating Dispersant for Solvent-Borne Coil Coatings & Multicolor Pigment Systems

ANJEKA 6401 acid-modified polyurethane dispersant for solvent-borne low/medium polarity systems

General Description:

Anjeka 6401 is a modified polyurethane copolymer solution with acidic functional groups, primarily designed for dispersion in solvent-based medium/low polarity resin coatings and ink systems, targeting both inorganic and organic pigments.

Product Data:

Chemical Composition: Modified polyurethane copolymer solution with acidic functional groups

The data provided on this sheet represents typical values and is not indicative of the product's technical specifications.

Storage and Transport:

Before use, thoroughly stir the solution. Separation or clouding may occur at temperatures below 0℃; heat to 30℃—40℃ and stir evenly. Storage time is not recommended to exceed 12 months.

Special Notes:

Due to its acidic nature, the product may catalyze the cross-linking of baking paint systems. Check the compatibility of the coating system during storage.

Application Guidelines:

Industrial Coatings and Printing Inks

Characteristics and Advantages:

This additive employs steric hindrance to disperse pigments, maintaining stability. The small particle sizes of the dispersed pigments prevent color floatation and blooming in multi-pigment systems, enhancing the coating's gloss, color intensity, transparency, and hiding power. The additive reduces viscosity, improving flow properties and allowing for higher pigment loading. When used in electrostatic high-speed rotation coating with inorganic pigments, it significantly reduces haze.

Additives & Instruments:

Application Sectors:

It is recommended to use this additive in solvent-based and solvent-free coatings, as well as printing inks, to stabilize inorganic pigments, especially titanium dioxide. Due to its anionic nature, the additive is an ideal choice for acid-catalyzed systems, such as coil coatings.

Recommended Levels:

Additive levels (based on pigment):

Titanium Dioxide: 2%—4%

Inorganic Pigments: 5%—10%

Organic Pigments: 10%—80%

The above data represents empirical levels; optimal levels should be determined through a series of experiments.

Incorporation and Processing Instructions:

For optimal performance, add the additive to the grinding media before incorporating pigments.
