Quick Penetrant T-70E (Wetting Agent OT) is a high-efficiency penetrating and wetting aid produced by Haian Guoli Chemical Co., Ltd., with CAS number 577-11-7. The product appears as a colorless to light yellow transparent viscous liquid, with good water solubility and compatibility. Its core component is di(2-ethylhexyl) sodium sulfosuccinate (70% solution), belonging to anionic surfactants, commonly known as docusate sodium, Aerosol OT, or AOT.
This product has four core advantages: first, rapid penetrating ability, which quickly reduces the surface tension of liquids, allowing the working solution to rapidly wet and penetrate into the substrate interior; second, excellent wetting and spreading performance on various substrates such as fibers, leather, and metals; third, it also has emulsifying and dispersing functions, effectively stabilizing the emulsion system; fourth, strong hard water resistance, maintaining stable effects even in hard water conditions, adapting to various water environments.
This product is produced by Guoli Chemical in strict accordance with quality standards, and each batch undergoes rigorous quality inspection to ensure stable and reliable performance. The product is supplied as a 70% active content solution, convenient for direct use or further compounding by customers.
Textile Printing and Dyeing: Suitable for pretreatment desizing, scouring, bleaching processes, and finishing stages, promoting uniform penetration of dyes and chemicals, improving dye uptake and color fastness, and enabling deep adsorption and spreading of finishing agents on fabrics.
Leather Processing: In wet processing stages such as soaking, degreasing, and tanning, it quickly wets leather fibers, shortens soaking and rehydration time, promotes chemical penetration, eliminates hard spots and color unevenness in leather, and improves leather yield and hand feel.
Papermaking Industry: Used as a wetting and penetrating aid in deinking waste paper to help ink detach from fibers; improves wetting and spreading of sizing agents and coating liquids on paper webs during sizing and coating processes.
Pesticide Formulations: Used as a wetting and penetrating synergistic component in emulsifiable concentrates, suspensions, aqueous solutions, etc., enhancing the spreading and absorption of pesticide liquids on plant leaves, improving efficacy and resistance to rainwater washing.
Coatings and Printing Inks: Accelerates wetting and dispersion of pigments and fillers, reduces floating color and flooding, enhances penetration and spreading of coatings on substrates, eliminates cratering and orange peel, and improves adhesion and gloss of the coating film.
Metal Cleaning and Household Cleaners: Enables cleaning solutions to quickly penetrate into oil stains, detach and disperse grease and dirt, significantly improving degreasing efficiency, suitable for various products such as laundry detergents and hard surface cleaners.
Petroleum Extraction: Used as a wetting reversal agent in oilfield chemical systems such as drilling fluids and oil displacement agents, reducing oil-water interfacial tension, improving wettability and displacement efficiency.
Emulsion Polymerization: Participates in polymerization reactions as a co-emulsifier and wetting agent, stabilizing primary latex particles, improving particle size uniformity and storage stability of the emulsion.
