• Applications

Special Features and Benefits

1. Improve wetting properties and reduce grinding time and viscosity of grinding materials.
2. Avoid floating color and blooming in multi-pigment systems.
3. Increase the gloss, color strength, transparency and hiding power of coatings.

• Recommended Use

Used for various types of concentrated color pastes containing resins, and can also be used for co-grinding of pigments in solvent-based coatings.

Addition amount

Calculated based on supply form:

Inorganic pigment: 10%-15%

Organic pigment: 30%-90%

Titanium dioxide: 3%-6%

Carbon black: 60%-120%

*. The above data are empirical dosages, and the optimal dosage needs to be determined through a series of tests.

Incorporation and Processing Instructions

To achieve the best performance, the additives should be added to the grind first, followed by the pigment. Premix the resin and solvent components of the grind, then slowly add the additives while stirring. Do not add the pigment until the additives are well mixed.
