Tech-598 is a dispersant containing acidic groups, suitable for both water and oil. It not only has good wetting properties, but also excellent anti settling ability. It has excellent viscosity reduction and dispersion ability for various inorganic pigments and fillers. At the same time, it has strong anti coagulation and anti coarsening ability for ground colorants, greatly increasing the storage stability of colorants. It can be widely used in SMC and BMC systems

Tech‑598 
Physical & Chemical Parameters
Composition: Acid‑group‑containing block copolymer of high‑molecular‑weight
Appearance: Pale yellow viscous liquid
Active Content: 100%
●  Tech‑598 is suitable for various polar systems, and performs exceptionally well in medium‑to‑high polarity systems. It can significantly improve the wetting and dispersing capacity of base materials for pigments and fillers, reduce system viscosity, enhance flowability, and shorten grinding & dispersion time
●  Tech‑598 is especially applicable for viscosity reduction, wetting and dispersion in SMC and BMC systems
