Dispersants

01 Overview

High-Performance Waterborne Pigment & Filler Dispersants are specially developed additives designed for efficient dispersion and long-term stabilization of inorganic pigments, organic pigments, and mineral fillers in water-based formulations. They help achieve excellent color development, improved gloss, reduced viscosity, and enhanced storage stability while maintaining compatibility with a wide range of binder systems.

Dispersants-3010

02 D-3010

Type: Hydrophobic Copolymer Dispersant

D-3010 is a high-performance, water-based dispersant for pigments and fillers based on a hydrophobic copolymer sodium salt. It offers high dispersion efficiency and low foaming properties, and can improve the flow and film-forming properties of coatings while effectively stabilizing slurry viscosity. It is widely used in pure acrylic, styrene-acrylic, and vinyl acetate-acrylic coating systems.

  •  Highly effective with inorganic pigments; offers high dispersion efficiency, and only a small amount is needed to achieve ideal dispersion results.
  • Highly versatile, suitable for formulation systems using various types of emulsions; provides good gloss retention, excellent water resistance, and aids in film formation and color development; suitable for coatings ranging from matte to glossy.
  • Excellent color development and gloss, low foaming, high efficiency, low foaming, high solids content, and an excellent cost-performance ratio, simplifying production operations.
  • Enhances film-forming and anti-corrosion properties.
  • Excellent compatibility with hydrophobic-modified polyurethane (HEUR) thickeners and leveling agents; good stability; overall excellent compatibility; and an excellent cost-performance ratio.

03 DP-3000

Type:Sodium Polycarboxylate

Dispersants are one of the key additives in coating formulations. Their primary function is to uniformly disperse pigments and fillers throughout the system and prevent particle re-agglomeration, thereby improving the stability, tinting strength, and application performance of the coating. DP-3000 is an anionic polymer dispersant widely used for the dispersion of pigments and fillers (such as titanium dioxide, kaolin, and heavy calcium carbonate) in water-based coating systems, as well as in water treatment and as a dispersant for ceramics.

  • Exceptional viscosity-reducing properties; disperses mineral powders such as calcium carbonate and kaolin
  • Excellent storage stability; prevents re-agglomeration
  • Alkali- and heat-resistant: Extremely high dispersion efficiency in alkaline process environments with a pH of 7.0–12.0

04 DP-3000N

Type:Ammonium Polycarboxylate

DP-3000N is an anionic polymer dispersant, specifically an ammonium polycarboxylate-based dispersant. It provides excellent dispersion performance for titanium dioxide and inorganic fillers, offering high dispersion efficiency and good storage stability. Due to the volatilization of the ammonium salts, it exhibits better water resistance than DP-3000.

  • Excellent water resistance
  • Outstanding viscosity-reducing properties; effectively disperses mineral powders such as calcium carbonate and kaolin
  • Alkali- and heat-resistant: exhibits extremely high dispersion efficiency in alkaline process environments with a pH range of 7.0–12.0
