Application field

Paint, adhesive and PVC plastisol

Product features and advantages

VOK ?- Disper 9076 makes pigment deflocculate through steric stabilization. At the same time, it can also make pigment particles have the same charge, and the generated repulsive force and steric hindrance stability prevent the occurrence of flocculation, so as to obtain the color appearance without blooming in the system containing multiple pigments.

Because the particle size of the deflocculating pigment is small, it can obtain high luster and improve the dyeing force. In addition, the transparency of transparent pigments and the hiding power of opaque pigments can also be improved. Due to its viscosity reducing effect, the flowability is improved, and the addition amount of pigment can be increased.

Recommended use

VOK ?- Disper 9076 is suitable for various pigments, especially for stable acid and neutral carbon black pigments. It can be used for solvent based and solvent-free coatings, adhesives and PVC plastisols. An important application field of the invention is to prepare solvent free pigment concentrate slurry for the above applications.

Recommended dosage

The amount of additives (purchased form) is based on the following pigments:

Titanium dioxide: 1-3%

Inorganic pigment: 5-10%

Organic pigment: 10-25%

Carbon black: 15-50%

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

Adding method and processing guidance

In order to obtain good performance, the additive must be added to the abrasive before the pigment is added.

SMC and pultrusion process

Product features and advantages

VOK ?- Disper 9076 can prevent the phase separation of different thermoplastics in various unsaturated polyesters, and is also suitable for low volatile formulations. Recommended for stabilizing organic pigments, especially acid and neutral carbon black, and for wetting carbon fibers.

Recommended dosage

5-30% of auxiliary dosage (purchased form) is based on organic pigment and carbon black and used to stabilize pigment.

0.5-1% auxiliary dosage (purchased form) is based on fiber content and used to wet carbon fiber.

0.3-1% of auxiliary agent dosage (purchase form) is based on resin dosage to prevent phase separation.

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

Adding method and processing guidance

In order to obtain good performance, the additive should be added to the resin mixture before mixing and adding solids.
