Dispersing agent DCA-597

Introduction

DCA-597 is a block-type polyurethane dispersant, widely applicable, suitable for both water-based and solvent-based systems, with strong dispersing capabilities for both inorganic and organic pigments. It exhibits excellent anti-floating and anti-flocculation properties.

Physicochemical Data

  • Chemical composition:High-molecular-weight block copolymer with pigment-affinitive groups

  • Appearance:Yellow transparent solution

  • Active content: 50%

  • Solvent:Mixed diester/diethyl-methyl amide = 2:1

Product features

  • DCA-597 is suitable for medium to high polarity systems and exhibits good compatibility with common coating resins, making it highly versatile in coating systems.

  • DCA-597 significantly enhances the wetting and dispersing capability of the base material for pigments, reducing system viscosity, improving flowability, and shortening grinding and dispersing time

Application areas

DCA-597 suitable for medium to high polarity systems

Addition Method

The dosage may vary depending on the specific system:

  • For inorganic pigments: 5% to 15%
  • For organic pigments: 30% to 50%
  • For carbon black: 50% to 100% (based on pigment surface area)

Dosage should be adjusted based on the surface area of the pigments used.

Packaging and storage:

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