• Applications

Special Features and Benefits：

1. Increase pigment concentration and increase production.
2. Shorten grinding time and reduce costs.
3. Improve rheological properties, reduce viscosity, and expand application adaptability.
4. Improve the application performance such as colorability, glossiness, transparency, etc.
5. Improve storage stability.

• Recommended Use

Surface treatment of aluminum silver paste, offset printing ink, news gravure toluene ink, various oily paints, oily color pastes and pigments.

• Addition amount

Generally, it is 3%~5% of the amount of pigment

*. The above data are the dosage ratios in the formula. The optimal dosage needs to be determined through a series of tests.

• Instructions for use

In order to obtain the best performance, the additives should be added to the grinding material first, and then the pigments. Premix the resin and solvent components of the grinding material, and then slowly add the additives under constant stirring. Do not add the pigment before the additives are mixed evenly.
