Rapid penetrant Fast T-40 (CAS No.: 577-11-7) appears as a colorless to slightly yellow transparent viscous liquid, belonging to the anionic surfactant category. Its chemical composition is sodium diisooctyl sulfosuccinate (also known as penetrant T, wetting agent OT, Aerosol OT/AOT). This product, leveraging its superior rapid penetration capability and wide compatibility, is regarded as a highly effective wetting and penetrating core auxiliary in numerous industrial fields such as textile dyeing and finishing, pesticide formulation, daily chemical cleaning, papermaking, and leather manufacturing.
The most prominent feature of Fast T-40 is its extremely fast penetration — it can achieve deep wetting of fibers and substrates in a very short time, significantly improving processing efficiency. At the same time, it possesses excellent wetting and spreading properties, effectively reducing the surface tension of liquids, ensuring uniform coverage of the working fluid on the substrate surface, and minimizing droplet roll-off. The product also exhibits outstanding chemical stability, maintaining high penetration activity in acidic, alkaline, and hard water systems without precipitation or failure, making it reliable even under complex process conditions.
In addition, Fast T-40 has broad compatibility, being compatible with anionic, nonionic, and most cationic systems, offering flexible formulation adaptability; its low foaming characteristic is particularly practical in continuous industrial operations, effectively reducing the need for defoamers, lowering costs, and simplifying operational procedures.
