Evonik Dynol 604 Gemini Superwetting Surfactant

Evonik Dynol 604 is a Gemini-type superwetting surfactant from the Dynol series, delivering ultra-low surface tension and rapid substrate wetting—even on low-energy surfaces like PE, PP, and silicones. It enhances coating uniformity, reduces defects, and improves pigment dispersion without foam or residue. Ideal for high-performance inks, coatings, and agricultural adjuvants where fast leveling and deep penetration are critical.

Features Of Evonik Dynol 604 Gemini Superwetting Surfactant

  1. Ultra-low surface tension (<25 mN/m in aqueous solution), enabling exceptional substrate wetting on low-energy surfaces.

  2. Gemini molecular architecture provides superior dynamic wetting performance compared to conventional single-chain surfactants.

  3. Excellent compatibility with a broad range of water-based formulations, including acrylics, polyurethanes, and epoxy dispersions.

  4. Low foaming profile—ideal for high-shear processes and applications requiring minimal foam generation.

  5. Effective at low use levels (typically 0.1–0.5 wt%), delivering cost-efficient performance without compromising formulation stability.

Typical Applications Of Evonik Dynol 604 Gemini Superwetting Surfactant

  1. Waterborne industrial coatings for metal, plastic, and wood substrates.

  2. High-performance inkjet inks, especially for non-porous or treated media.

  3. Agrochemical adjuvants to enhance spray coverage and foliar uptake.

  4. Printing and packaging coatings requiring rapid substrate penetration and leveling.

  5. Functional additives in concrete admixtures and construction chemical systems.
