The development of a new solvent-free, polymeric dispersant contains multiple anchoring groups and multiple solvation chains connected to the backbone. The major advantages of polymeric dispersants include long-term stabilization, prevention of pigment flocculation, providing a wetting effect, and a stabilization effect that is not sensitive to ions in the system. Solvent free type of new polymeric dispersant NUOSPERSE® FX 7500W contain multiple anchoring groups and multiple solvation chains connected to the backbone.
The major advantage of polymeric dispersant is as below :
• Long-term stabilization: The desorption is largely decreased because backbone restrict the departure of anchoring groups.
• Prevent pigment flocculation: multiple solvation chains provide better hindrance effect.
• Provide wetting effect: balance of hydrophilicity & hydrophobicity
• Stabilization effect is not sensitive to ions in the system.
