German technical background VOK ®- Disper P104 Wetting Dispersant

VOK ®- Disper P104 is used as a controlled flocculating wetting and dispersing agent for solvent based medium to high polarity coatings to prevent the floating color of titanium dioxide when mixed with color pigments.

Product Information

Chemical composition

Solution of low molecular weight unsaturated polycarboxylic acid polymer.

Typical Physicochemical Data

The data given in this data page are only typical values, not technical indicators of the product.

Acid value: 180 mg KOH/g

Density (20 ° C): 0.95 g/ml

Non volatile matter (10min, 150 ° C): 50%

Solvent: benzol/diisobutyl ketone 9/1

Flash point: 28 ° C

Storage and transportation

During transportation and storage, delamination and turbidity may occur, which shall be heated to 30-60 ° C and thoroughly mixed before use.

Special reminder

The compatibility is limited in the paint system with gasoline solvent as solvent or diluted with gasoline solvent. The auxiliary agent also has solvent free varieties, namely VOK ®- Disper P105。 

Application field

Coating industry

Features and Benefits

VOK ®- Disper P104 can provide a desired controlled flocculation of pigments, and build a bridge between pigment particles to form a three-dimensional network structure. This controlled flocculation of pigment effectively prevents floating color, blooming, sedimentation and sagging. VOK ®- Disper P104 is particularly suitable for medium to high polarity paint systems to prevent the floating color of titanium dioxide when mixed with color pigments. It has limited compatibility with gasoline solvents. In many cases, when used as an anti-corrosion primer, the corrosion resistance is improved.

Recommended dosage

The amount of additives (purchase form) is based on:

Inorganic pigment: 3-10%

Titanium dioxide: 0.5-2.5%

Organic pigment: 10-20%

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 to the grinding material first, and then the pigment.
