2026-05-17 官方文档 快速渗透剂,快T-50H

The core features of the rapid penetrant Quick T-50H include an exceptionally ultra-fast penetration rate (standard canvas sinking method < 5 seconds), extremely low surface tension (≤30 mN/m), and excellent wetting and spreading ability, making it a high-performance anionic surfactant.

Detailed Description

The chemical composition of Quick T-50H is sodium di(2-ethylhexyl) sulfosuccinate (DOSS), with CAS number 577-11-7. It appears as a colorless to pale yellow transparent liquid and is a classic high-efficiency anionic penetrant. Its most outstanding properties are its extremely low surface tension and high penetration rate—tested using the standard canvas sinking method, the penetration time is less than 5 seconds, allowing it to rapidly enter various fibers, porous substrates, and tiny gaps, significantly enhancing the diffusion efficiency of chemical agents within the substrate.

In addition to its permeability, Quick T-50H also exhibits excellent wetting and emulsifying capabilities. It can greatly reduce the solid-liquid contact angle, enabling good spreading and wetting even on hydrophobic surfaces (such as plant leaves, synthetic fibers, etc.). The product is designed to be low-foaming, ensuring that it does not interfere with process operations due to excessive foaming in practical applications. In terms of chemical stability, Quick T-50H is resistant to acids, alkalis, and hard water, making it suitable for a wide range of applications.

In terms of applications, Quick T-50H covers four core areas: textile printing and dyeing, pesticide formulations, leather processing, and industrial cleaning. In the textile industry, it serves as a penetrant in pretreatment, dyeing, and printing processes, helping to improve dye uptake and levelness; in pesticides, it is used as a wetting and penetrating synergist to enhance the adhesion and penetration of the spray liquid on target surfaces; in leather processing, it accelerates the penetration of chemicals into the leather fiber layers; in cleaning agents, it quickly penetrates the dirt-substrate interface to dislodge stubborn stains.

Application Recommendations

  • Textile Printing and Dyeing: Used as a high-efficiency penetrant in pretreatment, dyeing, and printing processes. The recommended dosage should be adjusted according to the process and fiber type, typically 0.1%~0.5% of the working solution. Best results are achieved under neutral to weakly acidic conditions.
  • Pesticide Formulations: Used as a wetting and penetrating synergist, with an addition amount generally 1%~5% of the total formulation, significantly improving the spreading and penetration of the spray liquid on plant leaves.
  • Leather Processing: Applied in wet processing steps such as soaking and degreasing, with a recommended dosage of 0.2%~1.0% to accelerate the penetration of the processing liquid into the leather fibers.
  • Industrial Cleaning: Used as a penetrating and decontaminating component in cleaning formulations, with a recommended dosage of 0.5%~3% of the total formulation, allowing rapid penetration beneath the dirt layer to promote stripping and dispersion.
  • Dilution Recommendation: This product is readily soluble in water; simply add water and stir to disperse and dissolve. Long-term use in strong acid (pH<3) or strong base (pH>12) environments is not recommended.

Precautions

  • Safety Protection: This product is irritating to the skin and eyes (GHS classification: Skin corrosion/irritation Category 2, Serious eye damage/eye irritation Category 2). Chemical protective gloves and safety goggles must be worn during operation to avoid direct contact.
  • Environmental Protection: Toxic to aquatic life (fish 96h LC₅₀ approximately 10~100 mg/L). Do not discharge the product or its waste liquid directly into water bodies. Dispose of waste liquid in accordance with local environmental regulations after use.
  • Storage Conditions: Store in a cool, dry, well-ventilated warehouse, keep containers sealed, avoid direct sunlight, and keep away from strong oxidizers and strong acids/bases.
  • First Aid Measures: In case of skin contact, rinse with plenty of running water and soap for at least 15 minutes; in case of eye contact, immediately flush with running water continuously for at least 15 minutes and seek medical attention; if swallowed, do not induce vomiting, seek medical attention immediately and show the product label.
