The chemical name of Fast T-70B is Sodium Dioctyl Sulfosuccinate (CAS No.: 577-11-7), with an effective active content of ≥70%, and appears as a colorless to light yellow transparent viscous liquid. Due to its high concentration and high viscosity, it is recommended to first dilute with warm water (40~50°C) to a 10%~20% stock solution, stir evenly, and then add it to the working system to ensure uniform dispersion and avoid local high concentration. This product is an anionic surfactant, compatible with anionic and nonionic additives, but should not be directly mixed with cationic additives to avoid precipitation or loss of efficacy.
\n\nAs a rapid penetrant, its outstanding feature is extremely strong penetration (≤5 seconds), surface tension can be reduced to ≤30 mN\/m, and the critical micelle concentration (CMC) is only 0.68 g\/L, meaning it can significantly reduce the surface tension of the system at very low dosages, achieving rapid wetting and penetration. It maintains stable chemical performance in hard water, acidic and alkaline media, with low foam, making it convenient for cleaning processes. For optimal results at normal usage concentrations, it is recommended to keep the pH of the working solution between 5 and 10.
\n\nIt is suggested to use the step-by-step scaling-up method to determine the optimal dosage: first conduct gradient tests in small samples (e.g., 0.05%, 0.1%, 0.2%, 0.5%), using penetration effect, wetting spreadability, and system stability as evaluation indicators, then determine the cost-effective dosage before scaling up to the production line. Excessive use not only increases costs but may also produce excessive foam or affect subsequent processes.

\n\n1. Textile Dyeing and Finishing (Recommended dosage: 0.1%~0.5% of working solution)
\nIn dyeing, scouring, and bleaching processes, add the diluted Fast T-70B directly to the dye bath or treatment solution. It quickly reduces the surface tension of the dye liquor, helping dyes and auxiliaries instantly wet and penetrate fibers, significantly improving level dyeing and reducing dye spots. In pre-treatment processes, it can be used together with scouring agents to accelerate alkali penetration and improve capillary effect.
2. Pesticide Formulations (Recommended dosage: 1%~5% of total formulation weight)
\nUsed as an efficient wetting and penetrating agent in formulations such as wettable powders (WP), suspension concentrates (SC), and water-dispersible granules (WDG). It can be added together with other additives before grinding or added later with stirring to enhance the spreading and penetration of the spray liquid on plant leaves and target surfaces.
3. Coatings and Inks (Recommended dosage: 0.05%~0.3% of total formulation weight)
\nAdded during the paint mixing stage of water-based coatings and inks, it significantly improves wetting and leveling on substrates, prevents surface defects such as craters and orange peel, and promotes rapid pigment dispersion. It is recommended to pre-mix with an appropriate amount of water before adding.
4. Industrial Cleaning and Metal Treatment (Recommended dosage: 0.2%~1.0%)
\nUsed in hard surface cleaning of metals, electronic components, etc., in combination with alkaline or acidic cleaners, it quickly removes oil stains and carbon deposits. In pickling, phosphating, and electroplating pre-treatment, it rapidly eliminates gas films on metal surfaces, ensuring a continuous and dense coating.
5. Papermaking and Leather Processing (Recommended dosage: 0.05%~0.5%, based on oven-dried pulp or leather weight)
\nIn papermaking, it is used for deinking, internal sizing, and coating to promote uniform distribution of chemicals; in leather processing, it is added during soaking, degreasing, and tanning stages to accelerate water and chemical penetration, reducing processing time.
6. Petroleum Extraction (Recommended dosage: 0.1%~0.5%)
\nUsed as a wetting reversal agent and cleanup additive, it is added when preparing fracturing fluids or oil displacement agents to reduce oil-water interfacial tension, improving water injection oil displacement efficiency and fracturing fluid flowback rate.
