Fast T-70B, chemically known as sodium dioctyl sulfosuccinate (CAS: 577-11-7), is a highly effective anionic surfactant that appears as a colorless to light yellow transparent viscous liquid. Its core advantages lie in excellent rapid penetration ability and superior wetting and spreading properties, which can quickly reduce interfacial tension while maintaining outstanding stability in acidic, alkaline, and hard water media, making it suitable for a wide range of working conditions.
In industrial applications, Fast T-70B, as a professional-grade penetrant and wetting agent, can significantly shorten process treatment time, improve the uniformity of chemical distribution, and enhance the emulsification and dispersion effects of the system. Whether in high-temperature dyeing, pesticide spraying, or hard surface cleaning scenarios, it plays an irreplaceable auxiliary function and is a key component in many industrial formulations.
| Application Industry | Specific Process/Use | Functional Effect |
|---|---|---|
| Textile Printing and Dyeing | Dyeing, printing, pretreatment | Rapidly reduces dye liquor surface tension, instantly wets and penetrates fibers, improves leveling and dye uptake rate, and reduces dye spots |
| Pesticide Formulations | Wettable powders, water suspensions | Enhances the spreading and penetration of the liquid on plant leaves and target surfaces, significantly improving efficacy |
| Coatings and Inks | Water-based coatings, water-based inks, pigment dispersion | Improves substrate wetting and leveling, prevents surface defects such as shrinkage holes and orange peel, and promotes rapid pigment dispersion |
| Daily Chemicals | Detergents, household cleaners, shampoos | Enhances decontamination and penetration, helping active ingredients enter dirt faster, improving cleaning effectiveness |
| Industrial Cleaning | Metal cleaning, electronic component cleaning | Strong penetration, quickly removes oil and carbon deposits, shortens cleaning time, and improves cleaning efficiency |
| Petroleum Extraction | Water flooding for oil displacement, fracturing fluid cleanup | Acts as a powerful wetting reversal agent and cleanup additive, reduces oil-water interfacial tension, improves oil displacement efficiency and flowback rate |
| Papermaking Industry | Deinking of waste paper, internal sizing, coating processing | Promotes uniform distribution of chemicals, improves sheet uniformity and surface strength |
| Leather Processing | Soaking, degreasing, tanning | Accelerates penetration of water and chemicals, shortens processing time, makes leather rewet more evenly, softer, and with finer grain |
| Metal Surface Treatment | Pickling, phosphating, electroplating pretreatment | Reduces surface tension of treatment liquid, quickly eliminates gas film on metal surface, ensures continuous and dense film layer, improves adhesion |
| Photosensitive Materials | Coating of photographic film and paper emulsion | Promotes rapid and uniform spreading of coating, eliminates bubbles and streaks, improves imaging clarity and quality |
Recommended Usage: Fast T-70B is typically used as a formulation component, with a recommended dosage of 0.1% to 2.0% of the total formulation (depending on the specific process and system). In textile printing and dyeing and industrial cleaning, it can be directly added to the working solution and stirred evenly before use; in pesticide and coating formulations, it is recommended to add during the grinding or mixing stage to fully utilize its wetting and dispersing effectiveness.
Compatibility: This product is anionic and can be compounded with nonionic and anionic surfactants to achieve synergistic effects. Avoid direct mixing with cationic auxiliaries to prevent precipitation or performance degradation.
