High-content Rapid Penetrant T-75A is an efficient anionic surfactant based on dioctyl sodium sulfosuccinate, featuring four core characteristics: rapid penetration, excellent wetting and emulsification, high chemical stability, and broad compatibility for formulation. It is a cost-effective industrial-grade rapid penetration aid.

Detailed Description

High-content Rapid Penetrant T-75A (CAS number: 577-11-7) belongs to the diester sodium salt of sulfosuccinate class of anionic surfactants. Its molecular structure, containing double ester groups and sulfonic acid groups, endows the product with outstanding interfacial activity. This product can significantly reduce the surface tension of liquids in an extremely short time, achieving deep and rapid wetting, greatly shortening the operation time of wet processing steps in textiles, papermaking, leather, etc., directly improving production efficiency.

The product maintains stable activity over a wide pH range and exhibits good tolerance to hard water and electrolytes, making it less prone to failure under complex working conditions. Additionally, its moderate foaming and easy foam control characteristics make it very suitable for continuous industrial production, avoiding issues such as tank overflow and metering deviations caused by excessive foam. The liquid viscosity is reasonably designed for easy pumping, metering, and automated dosing, further reducing operational difficulty.

Furthermore, T-75A's high active content means the active ingredients are more concentrated. Compared to ordinary penetrants, it requires lower dosage in actual use, resulting in significant overall cost benefits. The product can be compounded with anionic, nonionic, and some cationic systems to achieve synergistic effects, making it an ideal basic component for formulation engineers to flexibly build multifunctional additive systems.

Application Suggestions

Based on the product's core advantages of rapid penetration and excellent wetting, the following key application directions are recommended:

  • Textile Dyeing and Printing: Used as a pretreatment scouring agent and dyeing penetrating leveling agent to ensure dyes and auxiliaries quickly and uniformly penetrate into the fiber, improving dye uptake and color fastness.
  • Pesticide Formulations: Used as a tank-mix adjuvant or as an internal penetrating and spreading agent in formulations to enhance droplet spreading and translocation on plant leaf surfaces, significantly improving pesticide utilization.
  • Household and Personal Care Cleaning: Exerts deep penetration in laundry liquids and hard surface cleaners to quickly break down stubborn stains, improving detergency efficiency.
  • Papermaking and Leather: Accelerates the penetration of chemical liquors into pulp and leather fibers, shortening processing cycles, and improving product uniformity and physical properties.
  • Coatings and Inks: Improves pigment wetting and dispersion as well as substrate wetting, reducing surface defects like craters and pinholes, enhancing coating adhesion.

The recommended dosage should be determined by experiments based on specific formulations and process conditions. Generally, the addition amount as a penetration aid ranges from 0.1% to 2.0% (based on working solution).

Precautions

  • This product is irritating to skin and eyes (GHS classification: Skin irritation Category 2, Eye irritation Category 2). Protective gloves, goggles, and protective clothing must be worn during operation.
  • Avoid mixing or storing with strong oxidizers, strong acids, or strong bases to prevent adverse reactions.
  • Ensure good ventilation in the use area. Thoroughly wash hands and any contacted skin after operation.
  • In case of accidental skin or eye contact, immediately flush with plenty of water for at least 15 minutes. Seek medical attention if discomfort persists.
  • The product should be stored in a cool, dry, and well-ventilated indoor environment, away from direct sunlight and extreme temperatures, and keep the container tightly sealed.
