High-concentration rapid penetrant T-75A (CAS No.: 577-11-7), also known as rapid penetrant OT-75, Aerosol OT-75, sodium diisooctyl sulfosuccinate, etc., is a high-active-content anionic surfactant produced by Haian Guoli Chemical Co., Ltd. Its core chemical component is sodium dioctyl sulfosuccinate, appearing as a viscous liquid with high chemical stability. It remains active over a wide pH range and is resistant to hard water and electrolytes.
The prominent advantages of this product include rich active ingredients, lower dosage, and outstanding overall cost-effectiveness. Its low-foam microemulsion tendency is suitable for continuous production, and the appropriate viscosity facilitates pumping, metering, and automated dosing. Meanwhile, the product can be compounded with anionic, nonionic, and some cationic systems to achieve synergistic effects. It has high quality consistency and stable batch-to-batch performance.
The core function of high-concentration rapid penetrant T-75A is to rapidly reduce interfacial tension, achieving deep wetting and penetration. Its applications cover the following six major fields:
Textile Printing and Dyeing: Used as a pretreatment scouring agent, dyeing penetration leveling agent, and finishing wetting agent. It quickly reduces the surface tension of the dye liquor, promoting rapid and uniform penetration of dyes into the fiber interior, significantly improving dye uptake, color fastness, and fabric brightness.
Pesticide Formulations: Serves as a tank-mix adjuvant or a penetrating spreading agent added to formulations, enhancing the adhesion and penetration of the pesticide solution on plant leaves and target surfaces, reducing liquid loss, and effectively improving efficacy and utilization.
Daily Chemical Washing: Exerts deep penetration effects in products such as laundry detergents and hard surface cleaners, rapidly breaking down stubborn stains inside fibers and crevices, improving decontamination efficiency.
Papermaking Industry: Applied in waste paper deinking and pulp sizing processes. In paper coating, it improves the uniformity of coating penetration into the paper, enhances the bonding strength between coating and fibers, and increases the smoothness and printability of the finished paper.
Leather Processing: In soaking, degreasing, and fatliquoring processes, it promotes rapid and deep penetration of chemicals such as tanning agents and fatliquors along leather fibers, shortening wet processing time and giving the leather a soft, full hand feel.
Coatings and Inks: Improves the dispersion effect of pigments and fillers, enhances wetting and spreading ability on substrates, reduces surface defects such as craters and pinholes, and improves coating adhesion and leveling.
