Features Of Evonik Surfynol 485 Nonionic Gemini Surfactant

  1. Ultra-low surface tension—enables rapid substrate wetting and superior leveling in demanding formulations.

  2. Exceptional foam control—provides effective defoaming and anti-foaming without compromising performance.

  3. High hydrolytic and formulation stability—maintains efficacy across wide pH ranges (pH 2–13) and in electrolyte-rich systems.

  4. Low critical micelle concentration (CMC)—delivers high surfactant efficiency at low use levels.

  5. Nonionic, ethoxylate-free structure—ensures compatibility with ionic surfactants and avoids APEO-related regulatory concerns.

Typical Applications Of Evonik Surfynol 485 Nonionic Gemini Surfactant

  1. Water-based industrial coatings and paints—improves flow, leveling, and substrate wetting on low-energy surfaces.

  2. Agrochemical adjuvants—enhances spray droplet spreading and foliar uptake of active ingredients.

  3. Electronic cleaning formulations—supports residue-free, low-foam precision cleaning of sensitive components.

  4. Printing inks and inkjet media—reduces nozzle clogging and improves pigment dispersion stability.

  5. Specialty cleaning agents for metal and plastic substrates—boosts soil removal while minimizing foam generation.
