Dispersing agent DCA-8439

Introduction

DCA-8439 is a polymer-based hyperdispersant with multiple anchoring groups. It exhibits excellent wetting and dispersing ability for various organic pigments, has strong viscosity-reducing capabilities, and is particularly suitable for grinding high-pigment carbon black. It can significantly reduce the operational viscosity of the grinding system and increase pigment loading. When used in combination with pigment-derived viscosity reducers, it delivers even better results. Additionally, it has strong anti-agglomeration and anti-coarsening abilities, greatly enhancing the storage stability of the ground color paste and minimizing color floating during color adjustment.

  • Appearance:Yellow viscous liquid

  • Active content: 100%

  • Solvent: None

Product features

  • DCA-8439 significantly improves the wetting and dispersing ability of the base material towards pigment fillers, reduces system viscosity, enhances flowability, and shortens grinding and dispersing time. It works particularly well when used in combination with pigment-derived viscosity reducers.

  • DCA-8439 is suitable for medium polarity systems and exhibits good compatibility with common coating resins, making it highly versatile in coating systems.

  • DCA-8439 is a polymer-based hyperdispersant and offers excellent anti-coarsening abilities. Compared to small-molecule wetting dispersants, it greatly extends the storage stability of the ground color paste.

Application areas

  • Suitable for solvent-based coatings such as two-component polyurethane, alkyd, acrylic, polyester, and amino baking paints.

Addition Method

The dosage varies depending on the specific application system. For inorganic pigments, the recommended dosage is 10%-15%, for organic pigments, it is 30%-50% (based on the specific surface area of the pigment), and for carbon black, it is 70%-100%..

Packaging and storage:

25KG plastic drum, stored in a cool and dry place.
