The main ingredient of Rapid Penetrant T (Quick T-50) is Sodium Dioctyl Sulfosuccinate (anionic surfactant). Quick T-50 is a 50% aqueous solution form of this ingredient.

Detailed Description

The active chemical component of Rapid Penetrant T has the chemical name Sodium Dioctyl Sulfosuccinate, with CAS number 577-11-7. In the industry, this compound has multiple equivalent names, including: Sodium Diisooctyl Sulfosuccinate, Sodium Di(2-ethylhexyl) Sulfosuccinate, Dioctyl Sodium Sulfosuccinate, and the internationally common abbreviation AOT (Aerosol OT). These names all refer to the same chemical substance, differing only due to naming conventions and industry contexts.

Quick T-50 refers to the product where the above active ingredient is formulated with water to a approximately 50% concentration solution. Compared to the pure form, the 50% solution maintains high penetration performance while offering lower viscosity and better handling convenience, facilitating direct metering and use in industrial scenarios such as textile dyeing and printing, and pesticide formulations.

Application Suggestions

As an efficient anionic surfactant, its core function is to rapidly reduce liquid surface tension, achieving deep and fast penetration and wetting. It is primarily recommended for the following fields:

  • Textile Dyeing and Printing: Used as a penetrant in pretreatment, dyeing, and finishing processes to improve leveling of dyes and chemicals.
  • Pesticide Formulations: Used as a spreading and penetrating synergist to enhance adhesion and penetration of spray liquid on plant leaves and target pest surfaces.
  • Emulsion Polymerization: Used as an anionic emulsifier to stabilize monomer droplets and control latex particle size.
  • Leather Processing: Facilitates rapid penetration of chemicals into leather fibers in soaking, degreasing, dyeing, and other processes.
  • Paper Industry: Used in internal sizing or surface coating to improve uniform retention of sizing agents and functional additives.
