modified polyurethane copolymer dispersant for solvent-borne medium/low polarity resin systems

GENERAL DESCRIPTION

Anjeka-6402A is a modified polyurethane copolymer solution with acidic groups. It is a dispersant for solvent-borne medium/low polarity resin systems for coatings and inks, and is designed for the dispersion of inorganic and organic pigments.

PRODUCT DATA

Chemical composition: Acid-containing modified polyurethane copolymer solution.

Typical Physical and Chemical Data:

The data given on this data sheet are typical values and are not technical specifications of the product.

Appearance: Transparent yellow liquid

Acid value (mg KOH/g) 20 - 70

Density g/cm³ (23°C) 0.90 - 1.10

Viscosity cps (25℃) 5 - 250

Active ingredient (%) 50

Solvent Xylene

STORAGE and TRANSPORT

Please stir well before use, delamination or turbidity may occur when the temperature is lower than 0℃, heat to 30℃-40℃ and stir well.

Storage time is not recommended to exceed 12 months.

SPECIAL NOTES

The product has a certain acid value, which may catalyze the cross-linking of the baking paint system. The adaptability of the paint system during storage should be checked.

APPLICATION GUIDELINES

Coating industry and printing inks

Properties and Advantages:

The additive unflocates and stabilizes the pigments by means of spatial site resistance. Due to the small size of the deflocculated pigment particles, multi-color pigmented systems are free of color float and bloom. This increases the gloss, color strength, transparency and hiding power of the coating. The additive reduces viscosity, thus improving flow and increasing the amount of pigment added. When used for electrostatic high-speed spin-cup application of inorganic pigments, it significantly reduces haze.

APPLICATION SECTORS

This additive is recommended for stabilizing inorganic pigments, especially titanium dioxide, in solvent-borne and solvent-free coatings as well as in printing inks. Due to its anionic character it is ideal for acid-catalyzed systems (e.g. coil coatings).

RECOMMENDED LEVELS

The amount of additive (in purchased form) is based on the pigment:

Titanium dioxide: 2%-4%

Inorganic pigments: 5%-10

Organic pigments: 10%-80

The above data are empirical and the optimum amount 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.
