Rapid Penetrant T-70E, with the chemical name sodium di(2-ethylhexyl) sulfosuccinate, is an anionic surfactant. It appears as a colorless to light yellow transparent viscous liquid. Its core advantages lie in its excellent rapid penetration ability and superior wetting and spreading performance, which quickly reduce liquid surface tension, allowing the working fluid to rapidly wet and penetrate into the substrate interior. It also possesses good emulsifying and dispersing functions and hard water resistance, maintaining stable effects under various water quality conditions.
In textile printing and dyeing, this product is used throughout core processes such as pre-treatment desizing, scouring, bleaching, and finishing, accelerating the penetration of alkali, bleaching, or dyeing liquids into fiber interiors, significantly improving dye uptake and color fastness. In leather processing, it is applied in wet processing stages like soaking, degreasing, and tanning, shortening soaking and re-wetting time, eliminating leather hard spots and color unevenness, and improving leather yield and hand feel.
In industries such as pesticide formulations, coatings, and inks, this product serves as a wetting and penetrating synergist, significantly reducing the contact angle of the liquid on target surfaces, enhancing spreading and absorption. In fields like petroleum extraction, metal cleaning, and household cleaning agents, its synergistic effect of rapid penetration and emulsification effectively improves degreasing efficiency, stain removal speed, and displacement efficiency, making it highly versatile.

Rapid Penetrant T-70E has good water solubility and compatibility, and can be compounded with nonionic and anionic surfactants and various auxiliaries. In textile and leather processing, it is recommended to adjust the dosage according to the process liquor ratio and fiber type. In pesticide and coating formulations, it can be added as needed as a wetting and penetrating synergist. Its good hard water resistance makes it especially suitable for industrial environments with complex water quality conditions.
