Special reminder

The surface treatment of some organic pigments will have a bad effect on the performance of the additive. In this case, the same type of untreated pigment can be used.

Application field

Coating industry

Product features and advantages

VOK ?- Disper 182 enables pigment to deflocculate through steric stabilization. Because the particle size of the deflocculating pigment is small, it can obtain high luster, enhance color strength, and improve transparency or hiding power. Due to the reduction of viscosity, the flowability is improved and the content of pigment can be increased.

Recommended use

VOK ?- Disper 182 is widely used for solvent based and water-based systems. It can be used alone or with VOK ?- Disper 108 is used together to produce an economical solvent based pigment concentrate.

Recommended dosage

Additive dosage (purchase form) is based on pigment:

Inorganic pigment: 15-20%

Titanium dioxide: 4-5%

Organic pigment: 30-60%

Carbon black: 80-100%

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. Premix the resin and solvent components in the abrasive, and then slowly add VOK in the stirring state ?- Disper 182。 Pigments can only be added after the auxiliaries are completely dispersed and uniform.
