QM-1792 Water-based Dispersant

Product Overview:

QM-1792 is a high-molecular-weight block copolymer that deflocculates pigments through steric hindrance, providing different pigments with the same charge. This prevents pigments with different charges from potentially co-flocculating, thus preventing floating color and blooming phenomena. It is suitable for water-based coatings, printing inks, thermoplastics, unsaturated polyester systems, or gel coats, and is used to disperse inorganic pigments, organic pigments, and carbon black. This additive is specifically developed for dispersing and stabilizing water-based effect pigments.

Physicochemical Parameters:

Composition: Polymer copolymer containing hydroxyl groups

Appearance: Yellow transparent liquid

Active content: >97%

Amine value: <5mgKOH/g

Acid value: <5mgKOH/g

Product Characteristics:

QM-1792 is a versatile, widely applicable pigment, particularly suitable for stabilizing aluminum powder and pearlescent powder.

QM-1792 is a water-based polymeric dispersant with high solids content, free of water and co-solvents. It is suitable for zero-VOC or low-VOC water-based coatings and printing inks, as well as resin-containing or resin-free pastes.

QM-1792 exhibits excellent dispersion stability, providing high gloss, excellent viscosity reduction, anti-flocculation, and anti-floating properties.

QM-1792 is especially recommended for dispersing and stabilizing water-based effect pigments, such as water-based aluminum silver paste and water-based pearlescent powder.

Application Systems:

Suitable for various water-based coatings, especially for the stabilization of effect pigments.
