Product Information

Chemical composition

Typical Physicochemical Data of Modified Styrene Maleic Acid Copolymer Solution The data given on this data page are only typical values, not technical indicators of the product.

Acid value: 10 mg KOH/g

Density (20 ° C): 1.06 g/ml

Non volatile matter (10 min., 150 ° C): 40%

Solvent: water

Storage and transportation

When the temperature is below 0 ° C, stratification or turbidity may occur. Heat to 20 ° C and mix well.

Application field

Paint and printing ink

Product features and advantages VOK ®- Disper 2015 deflocculates pigments through steric stabilization. Because the particle size of the deflocculating pigment is small, it can obtain high luster, improve the tinting power, and improve the transparency or coverage. Due to VOK ®- The viscosity reducing effect of Disper 2015 can improve the leveling performance and increase the amount of pigment added.

Recommended use

Coil coating

Wood and furniture coatings

Architectural coatings

Leather coating

Printing ink

VOK ®- Disper 2015 is especially recommended for the production of stable resin free pigment concentrate slurry to prevent floating color of water-based paint and printing ink. Pigment dispersion can only be carried out in water (without resin, amine or cosolvent). VOK ®- Dispatch 2015 contains no VOC and is only applicable to water-based systems.

Recommended dosage

Additive dosage (purchase form) is based on pigment:

Inorganic pigment: 12.5-30%

Titanium dioxide: 2.5-7.5%

Organic pigment: 30-75%

Carbon black: 100-150%

The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.

The addition method and processing guidance for the production of resin free pigment concentrate only need to mix the additives with water first, and only after the additives are evenly dispersed can the pigments be added. Pigment dispersion can only be carried out in water (without resin, amine or cosolvent).

an adhesive

Product features and advantages

VOK ®- Dispatch 2015 enables the pigment and filler to de flocculate through the role of steric stability. The additive can reduce the viscosity, thereby making the adhesive product easy to process, or increasing its filling amount.

Recommended use

VOK ®- Disper 2015 is recommended for all water-based dispersion adhesives. The additive contains no VOC and is only applicable to water-based systems.

Recommended dosage

Additive dosage (purchase form) is based on pigment:

Titanium dioxide: 2.5-7.5%

Carbon black: 100-150%

Inorganic filler: 0.5-1%

The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

In order to obtain good performance, additives must be added into the system first, and then the pigments and fillers.
