Fast T-70B, with the chemical name Sodium dioctyl sulfosuccinate (CAS No.: 577-11-7), is an anionic surfactant. It appears as a colorless to light yellow transparent viscous liquid. The diester and sulfonate groups in its molecular structure endow it with strong interfacial activity, enabling rapid adsorption at liquid-solid and liquid-air interfaces, significantly reducing interfacial tension, thus achieving instant penetration and efficient wetting.
Thanks to its unique chemical structure, Fast T-70B maintains excellent stability in acidic, alkaline, and hard water environments. This gives it a significant advantage over many common anionic surfactants, allowing stable performance under complex conditions and offering a wide range of applications.
In addition, Fast T-70B exhibits outstanding emulsifying and dispersing properties, facilitating uniform dispersion of oil and water phases in mixed systems to form stable emulsions. This is particularly prominent in applications requiring multiphase coexistence, such as pesticide formulations, coatings, and inks.
| Feature | Specific Performance |
|---|---|
| Rapid Penetration | Excellent penetrating ability, quickly reduces interfacial tension for efficient wetting, helping active ingredients instantly penetrate into the target object |
| Superior Wetting | Strong wetting and spreading performance on various substrate surfaces, significantly improving treatment uniformity and reducing surface defects |
| Good Emulsification | Excellent emulsifying and dispersing capabilities, aiding in the formation of stable and uniform mixed systems |
| Wide-Range Tolerance | Maintains excellent stability in acidic, alkaline, and hard water media, suitable for a wide range of operating conditions |
Based on the above characteristics, Fast T-70B is widely used in the following fields:
