What are the physicochemical technical parameters of Quick T-70B, Rapid Penetrating Agent T, and Wetting Agent OT?

Quick T-70B (Dioctyl Sodium Sulfosuccinate) is a highly efficient anionic surfactant. Its core physicochemical characteristics are: HLB value 10-13, pH of 1% aqueous solution 5.0~7.0, penetration power ≤5 seconds, surface tension ≤30 mN/m, CMC value 0.68 g/L. It is a low-foam, acid-alkali and hard water resistant fast-penetrating wetting agent.

Detailed Description

Quick T-70B, chemically known as Dioctyl Sodium Sulfosuccinate (CAS No.: 577-11-7), has a molecular formula C₂₀H₃₇NaO₇S and a molecular weight of 444.56. This product appears as a colorless to light yellow transparent viscous liquid, with an active content ≥70.0%, and belongs to the anionic surfactant category. Its most outstanding performance is extremely fast penetration speed—the penetration power measured by the standard canvas sedimentation method is ≤5 seconds, far superior to conventional penetrants, thanks to its unique diester structure that rapidly forms directional adsorption at the interface, significantly reducing interfacial tension.

In terms of solubility and stability, this product is readily soluble in water. The pH value of a 1% aqueous solution is between 5.0 and 7.0, near neutral, making it environmentally friendly for use. It also exhibits excellent chemical stability, resisting acids, alkalis, and hard water without easy failure. Its foaming property is low-foam type, suitable for industrial scenarios requiring rapid defoaming or where large amounts of foam are undesirable, such as spray cleaning and high-speed coating processes.

This product is produced by Guoli Chemical in strict accordance with national standards, available in 50kg, 200kg, and 1000kg packaging. As a representative product of domestic Rapid Penetrating Agent T (Wetting Agent OT), its quality indicators are stable, and it has mature applications in ten major fields including textiles, pesticides, coatings, daily chemicals, and industrial cleaning.

Technical Parameters

Application Suggestions

Based on the above physicochemical parameters, the use of Quick T-70B can refer to the following suggestions:

• Recommended Dosage: The recommended addition amount in general formulations is 0.1%~1.0% (based on total system weight), which can be optimized through gradient trials according to penetration or wetting requirements. In textile pretreatment, the padding section typically uses 0.5~2.0 g/L.
• Usage Method: This product can be directly added to the aqueous phase with stirring to dissolve, or compounded with other surfactants in the formulation. It shows significant synergistic effects especially with nonionic surfactants, enhancing overall wetting and penetrating ability.
• Applicable pH Range: Due to its acid and alkali resistance, it can stably exert penetration and wetting effects within the pH range of 3~12, suitable for acidic, neutral, and alkaline working fluid systems.
• Compatibility: As an anionic type, it should not be directly mixed with high concentrations of cationic surfactants to avoid precipitation or reduced efficacy. If compounding is needed, it is recommended to conduct a small-scale compatibility test first.

Precautions

• Safety Protection: This product is harmful if swallowed, irritating to skin and eyes, and may cause respiratory irritation. Protective gloves and goggles should be worn during operation, and use in a well-ventilated area. Avoid inhalation of vapors or spray.
• Storage Conditions: Store in a cool, ventilated place, keep the container tightly closed, and keep away from high temperatures and ignition sources. Use as soon as possible after opening.
• Emergency Treatment: In case of skin contact, immediately rinse with plenty of water and remove contaminated clothing; in case of eye contact, rinse carefully for several minutes and seek medical advice if irritation persists; if swallowed, do not induce vomiting, rinse mouth and seek medical attention immediately.
• Packaging Specifications: Guoli Chemical provides three packaging options: 50kg, 200kg, and 1000kg, which can be selected according to actual usage.
