Super penetrating agent JFC-E (chemical name: Dioctyl sodium sulfosuccinate, also known as Rapid Penetrant T/Penetrant OT/Aerosol OT, CAS number: 1639-66-3) is an anionic surfactant with an effective content of ≥99%, appearing as a light yellow to colorless transparent liquid. Its penetrating power is extremely strong, with a penetration time measured by the standard canvas sedimentation method of ≤5 seconds. The surface tension of a 1% aqueous solution is as low as 28~32 mN/m, endowing the working fluid with excellent instantaneous wetting and penetrating capabilities. This product is resistant to acids, alkalis, and hard water, has excellent chemical stability, and is compatible with various ionic auxiliaries. It is an indispensable high-efficiency penetrating auxiliary in many industries such as textiles, leather, and cleaning.
Due to the high active content and outstanding penetration efficiency of JFC-E, a relatively small dosage can achieve significant effects in practical use. When preparing the working fluid, it can be diluted with water or directly added to the system and stirred evenly, without the need for special equipment. For continuous production lines, it is recommended to use a metering pump to precisely control the addition amount to ensure consistent results between batches. The working fluid temperature is generally controlled between 20~60°C to fully exert its penetration performance. It has excellent alkali resistance and can tolerate NaOH solution environments as high as 200 g/L.
It should be specifically noted that the Guoli Chemical product database does not contain precise recommended dosage values for each specific process. The following dosage ranges are compiled based on the product's physical and chemical properties and general industry practical experience. Users should conduct small-scale experiments based on their own process conditions before actual production to determine the most suitable addition ratio.
