Name: Evonik TEGO Dispers 628 Dispersant
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik TEGO Dispers 628 Dispersant

High-efficiency polymeric dispersant based on controlled radical polymerization (CRP) technology.
Excellent stabilization of inorganic pigments and fillers in aqueous systems, including TiO₂, iron oxides, and carbon black.
Low foaming and good compatibility with common waterborne resins (e.g., acrylics, PUDs, and styrene-acrylics).
Enables high pigment loading while maintaining low viscosity and long-term storage stability.
Non-ionic character ensures broad formulation tolerance and reduced sensitivity to electrolytes and pH shifts.
