​BYK DISPERBYK-2205 Wetting Dispersing Agents

BYK DISPERBYK-2205 is a high-molecular-weight copolymer Wetting Dispersing Agents designed for solvent-based and solvent-free coatings, inks, and jet inks. It stabilizes inorganic/organic pigments via steric hindrance and charge equalization, ensuring uniform dispersion while reducing viscosity and thixotropy. Its neutral pH profile makes it compatible with acid-catalyzed systems

Effect of BYK DISPERBYK-2205 Wetting Dispersing Agents

  1. Universal Stabilization - Effective for both inorganic and organic pigments, including carbon black

  2. Viscosity Control - Reduces grinding viscosity and eliminates thixotropic behavior

  3. Neutral Compatibility - Suitable for acid-catalyzed systems due to balanced acid/amine values

  4. Process Efficiency - Enables higher pigment loading in concentrates

  5. UV/Solvent Adaptability - Works in UV-curable and solvent-based ink system

Typical Applications of BYK DISPERBYK-2205 Wetting Dispersing Agents

  1. Industrial Coatings - High-gloss finishes for automotive and coil coatings

  2. Printing Inks - Solvent-based flexographic and UV inkjet inks for packaging

  3. Wood Finishes - Acid-cured furniture coatings with low haze

  4. Pigment Concentrates - High-load dispersions for color matching

  5. Ceramic Inks - Stable pigment suspensions for high-temperature applications
