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.
