The chemical full name of Quick Penetrant T-70E (Wetting Agent OT) is Di(2-ethylhexyl) sulfosuccinate sodium salt (CAS: 577-11-7), which belongs to the anionic succinate sulfonate surfactant family. The product is a 70% active concentration solution, appearing as a colorless to light yellow transparent viscous liquid with slight hygroscopicity. Its core physicochemical features include: extremely low surface tension (≤30 mN/m), giving it excellent penetrating and wetting ability; resistance to hard water, acids, and alkalis (resistant to 80~100g/L NaOH), and low foam characteristics, making it very suitable for industrial fields with high requirements for wetting and penetration, such as textiles, pesticides, and emulsion polymerization.
According to the Guoli Chemical product database, the standard test data at 25°C covers physical properties, surface activity, and component purity. Among them, penetrating power is one of the core indicators to measure its performance. Using the standard canvas sedimentation method, the penetration time of a 1% aqueous solution is ≤5 seconds, reflecting the product's high-speed penetration characteristics. In addition, the active substance content (diester content) is ≥70%, ensuring sufficient effective ingredients in final applications.
In terms of application stability, its acid value (≤2 mg KOH/g) and monoester content (≤1.5%) are strictly controlled to ensure batch-to-batch performance stability. The product also complies with relevant environmental and safety regulations, with heavy metal content (≤10 mg/kg) and arsenic content (≤2 mg/kg) at low levels, meeting the requirements for cleaner production in modern industry.
