QM-1729 Water-based Dispersant

Product Overview:

QM-1729 is a polymeric superdispersant containing multiple pigment-affinity groups. It exhibits excellent dispersion effects on organic pigments, carbon black, and inorganic pigments, and demonstrates good viscosity reduction. The resulting color pastes have low viscosity and exhibit certain thixotropy (no thickener is required, providing excellent anti-settling and anti-water separation effects). It can be used to prepare water-based resin-free color pastes. It is suitable for water-based coatings and water-soluble coatings.

Physicochemical Parameters:

Composition: High molecular weight block copolymer containing pigment-affinity groups

Appearance: Yellow to brownish-yellow transparent liquid

Active component: 40%

Solvent: Water

Product Characteristics:

It can be used for dispersing various organic pigments, inorganic pigments, carbon black, and titanium dioxide;

It belongs to the category of high-molecular-weight superdispersants and has excellent wetting properties. Compared with small-molecule wetting and dispersing agents, it has a superior ability to prevent coarsening;

It has a good viscosity-reducing effect, and the prepared color paste has a certain degree of thixotropy and good anti-settling properties;

The prepared color paste has good storage stability and is suitable for water-based resin-free color pastes.

Application Systems:

Suitable for water-based systems, water-soluble systems, etc.

Recommended Dosage:

Percentage of effective dispersant content in pigment weight:
Titanium dioxide: 2-5%
Inorganic pigments: 3-10%
Transparent iron oxide: 40-60%
Organic pigments: 10-40%
Ordinary carbon black: 15-40%
High-pigment carbon black: 40-75%
