Features and Benefits

The additive can deflocculate the pigment by stabilizing the steric hindrance. Because the particle size of the deflocculating pigment is small, it can obtain high gloss and improve color intensity. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are also improved. Due to the reduction of viscosity, the flowability is improved and the content of pigment can be increased.

Recommended use

The additive is recommended for all water-based, solvent based and solvent-free systems to stabilize inorganic pigments, especially titanium dioxide.

Recommended dosage

The amount of additives (purchase form) is based on:

Inorganic pigment: 5-10%

Titanium dioxide: 1.5-2.5%

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 the auxiliary agent in the state of continuous stirring. Do not add pigments when the auxiliaries have not been completely dispersed evenly.
