High-concentration fast-penetrating agent T-75A (sodium diisooctyl sulfosuccinate) is a highly efficient anionic surfactant with sodium sulfosuccinate diester as the core component. With its excellent fast-penetrating ability, superior wetting and emulsifying performance, and broad chemical compatibility, it has become an indispensable key auxiliary agent in multi-industry wet processing and formulation recipes. This product can achieve deep wetting in a short time, significantly reducing processing time and improving production efficiency. It has a high active substance content and outstanding overall cost-effectiveness.
Since the product maintains stable activity over a wide pH range and is resistant to hard water and electrolytes, it can be compounded with anionic, nonionic, and even some cationic surfactant systems to achieve synergistic effects. Its low-foam microemulsion tendency results in moderate foam under dynamic conditions, making it easy to control foam and highly suitable for continuous production scenarios.
| Industry | Specific Application Process | Function |
|---|---|---|
| Textile Printing and Dyeing | Pretreatment scouring, dyeing penetration and leveling, finishing wetting | Rapidly reduces the surface tension of the dye liquor, promoting fast and uniform penetration of dyes into the fiber interior, significantly enhancing dye uptake, color fastness, and fabric brightness |
| Pesticide Formulations | Tank mix adjuvants, penetration and spreading agents in formulations | Enhances the adhesion and penetration ability of the spray liquid on plant leaves and target surfaces, reducing runoff and effectively improving efficacy and utilization rate |
| Daily Chemical Washing | Laundry liquid, hard surface cleaners, personal care products | Provides deep penetration, rapidly breaking down stubborn stains inside fibers and crevices, improving detergency efficiency and imparting a fresh feel to fabrics |
| Papermaking Industry | Waste paper deinking, pulp sizing, paper coating | Improves the uniformity of coating penetration into the paper sheet, enhances the bonding strength between the coating and fibers, and increases the paper's smoothness, gloss, and printability |
| Leather Processing | Soaking, degreasing, fatliquoring, tanning processes | Promotes rapid and deep penetration of chemicals such as tanning agents, fatliquoring agents, and retanning agents along the leather fibers, shortening wet processing time and making the leather soft, plump, and elastic |
| Coatings and Inks | Pigment wetting and dispersion, substrate wetting, leveling aids | Improves the dispersion effect of pigments and fillers, enhances wetting and spreading ability on the substrate, reduces surface defects such as craters and pinholes, and improves coating adhesion and leveling |
In practical applications, it is recommended to determine the dosage based on specific process requirements. Generally, when used as a wetting and penetrating agent, adding 0.1% to 1.0% of T-75A can achieve significant effects. For difficult wetting scenarios (such as low-surface-energy substrates or dense fibers), the dosage can be appropriately increased. The product is in liquid form with suitable viscosity, facilitating pumping and automatic metering feeding, making it suitable for large-scale continuous production. When compounding with anionic or nonionic systems, it is advisable to conduct small-scale compatibility tests first to determine the optimal ratio.
