German Technical Background VOK-118 Wetting Dispersant Suitable for Fillers and Inorganic Pigments Replaces BYK-118

German technical background VOK®- Disper 118 Wetting Dispersant

Features and Benefits

VOK®- Disper 118 was specifically developed for stabilizing titanium dioxide. Different from other additives, the additive can stabilize the acidic, alkaline and neutral

Titanium oxide. In addition, VOK®- Disper 118 is also ideal for fillers, matting powders, inorganic pigments, transparent iron oxides, and effect pigments.

VOK®- Disper 118 can effectively reduce the viscosity of the abrasive, thus increasing the pigment/filler content in the pigment/filler concentrate. The additive can increase the

Gloss and reduce fog shadows. Since there is no negative impact on metal adhesion, VOK®- Disper 118 can also be used for coatings applied directly to metal surfaces.

Recommended dosage

Additive dosage (purchase form) is based on pigment

Inorganic pigment: 3-6%

Titanium dioxide: 1-2.5%

Effect pigment: 0.5-2.5%

Filler: 0.5-2%

The above data are empirical dosage, and good dosage shall be determined through a series of tests.

Addition method and processing guidance

In order to obtain good performance, additives shall be added to the grinding material first, and then the pigment shall be added. First grind

Then slowly add the auxiliary agent under constant stirring. Pigment shall not be added before the additives are uniformly mixed
