AgeSin® DP-S2740 EC is a 100% active, solvent‑free polymeric dispersant based on a phenolic derivative modified polyether structure. It is particularly suitable for dispersing carbon black and organic pigments, especially difficult‑to‑disperse organic pigments such as polycyclic and phthalocyanine types. The product is designed for use in waterborne pigment concentrates, as well as in waterborne and solvent‑based printing inks.
AgeSin® DP-S2740 EC
(High Efficiency Dispersant for Carbon Black & Organic Pigments)
AgeSin® DP-S2740 EC is a 100% active, solvent-free polymeric dispersant based on a phenolic derivative modified polyether structure. It is specifically engineered to deliver superior dispersion performance for carbon black and organic pigments, particularly difficult-to-disperse types such as polycyclic and phthalocyanine pigments.
As a non-ionic, high-efficiency dispersant, AgeSin® DP-S2740 EC offers a compelling combination of high pigment loading capability, rapid viscosity reduction, broad temperature stability, and excellent compatibility with both waterborne and solvent-based systems. It serves as a direct and cost-effective alternative to Clariant Dispersogen 2774 (CAS No 55845-06-2).

Incorporation Method:
For best results, pre-dissolve AgeSin® DP-S2740 EC in a glycol solvent (e.g., ethylene glycol or propylene glycol) before use to ensure optimal incorporation into the millbase. For water-based pigment preparations and printing inks, add the dispersant before the grinding step to maximize wetting and dispersion efficiency.
Packaging: 25 kg drum
Storage: Keep in a dry, clean, well-ventilated warehouse. Avoid exposure to light and heat. Protect from leakage, rain, and direct sunlight during transportation. Keep container tightly closed when not in use.
Shelf Life: 12 months in original unopened packaging. Products beyond the storage period may be used after inspection.
AgeSin® DP-S2740 EC is designed to meet or exceed the performance of Clariant Dispersogen 2774, offering comparable pigment wetting, dispersion stability, and viscosity reduction at a competitive price point.
The product is built on a well-established non-ionic polymeric dispersant platform (phenolic derivative modified polyether) with decades of proven performance in waterborne pigment preparations and printing inks. It shares the same CAS number (55845-06-2) and chemical type as the benchmark.
The underlying chemistry (Formaldehyde, polymer with nonylphenol and oxirane) is compliant with key global chemical inventories including TSCA (USA), REACH (Europe), IECSC (China), and more.
A: The CAS number is 55845-06-2 (Formaldehyde, polymer with nonylphenol and oxirane), which is the same as the benchmark product Clariant Dispersogen 2774.
A: Yes. AgeSin® DP-S2740 EC is designed for waterborne pigment concentrates and printing inks, but also shows broad compatibility with solvent-based systems due to its non-ionic nature and solubility in alcohols, ethylene glycol, and propylene glycol.
A: The product is particularly effective for carbon black and organic pigments, especially difficult-to-disperse types such as phthalocyanine (blue & green), polycyclic pigments, and other high-performance organic pigments.
A: AgeSin® DP-S2740 EC is formulated to be APEO-free and carries no hazard label (hazard label-free), making it suitable for applications requiring strict environmental and safety compliance.
A: The shelf life is 12 months when stored in the original unopened packaging under recommended conditions (dry, well-ventilated warehouse, away from light and heat).
A: Yes. AgeSin® DP-S2740 EC exhibits low foaming behavior during pigment paste fabrication, which simplifies processing and reduces the need for additional defoamers.
A: For best results, pre-dissolve the dispersant in a glycol solvent (ethylene glycol or propylene glycol) before adding pigment. It should be added before the grinding step to maximize wetting and dispersion efficiency.
A: Yes. AgeSin® DP-S2740 EC is especially recommended for use in concentrates for in-plant tinting (factory-level tinting systems).
