• Applications

Special Features and Benefits

A polymeric dispersant that exhibits excellent color development and high gloss in water-based resin-free systems for high-surface-area carbon black/difficult-to-disperse organic/inorganic pigments. It allows for increased pigment addition while maintaining low viscosity, good flowability, and storage stability.

• Recommended Use

1. In water-based paints and inks, for grinding and dispersing carbon black and organic and inorganic pigments.
2. Exhibits good compatibility with waterborne acrylic resin emulsions and waterborne polyurethane resins.
3. Preparation of various high-end resin-free waterborne color pastes.

Addition amount

Recommended dosage calculation formula:

Dispersant dosage (g) = [Specific surface area of pigment (m2/g)÷500]×Pigment weight (g)

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

Incorporation and Processing Instructions

First, dissolve the HH-2511 dispersant in the mixture of grinding base (water), then add the pigment and grind.
