Product Description
OT-75 Surfactant: High-Performance Dispersant and Emulsifier for Coatings and Inks
Surfactant OT-75 (Dioctyl sulfosuccinate sodium salt) is a highly efficient anionic surfactant. This clear liquid (colorless to light yellow) contains approximately 75% active ingredient and features extremely low surface tension with exceptional penetration properties. As a versatile functional additive, OT-75 is widely used in coatings, inks, pesticides, textiles, and dyeing applications—particularly where rapid wetting and penetration are required.

Performance Characteristics & Applications
  • Superior wetting and penetration: Dramatically reduces liquid surface tension and rapidly wets difficult surfaces. Commonly used as a wetting/spreading agent in pesticide formulations.
  • Coatings and inks performance: Functions as an effective dispersant and emulsifier—reduces system viscosity, enhances pigment dispersion stability, prevents sedimentation/floating, and improves leveling for uniform coating surfaces.
  • Textile dyeing applications: Serves as penetrating and leveling agent, facilitating dye penetration into fibers while improving dyeing uniformity and color fastness. Also enhances pretreatment processes with scouring/bleaching agents.
Key Advantages
  • Exceptional wetting/penetration capabilities for difficult-to-wet surfaces
  • Excellent compatibility with anionic, nonionic surfactants and additives
  • Environmentally friendly with good biodegradability and low toxicity
