QM-1790A Water-based Dispersant

Product Overview:

QM-1790A is a polymeric superdispersant containing multiple pigment-affinity groups. It exhibits excellent dispersion effects on organic pigments, carbon black, and inorganic pigments, with outstanding viscosity-reducing properties. The resulting color pastes also demonstrate good storage stability. 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 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 molecular weight wetting and dispersing agents, it has a superior ability to prevent coarsening;

It has good viscosity reduction effect, and the prepared color paste has 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%
Regular carbon black: 15-40%
High-pigment carbon black: 40-75%
