Features Of Evonik Surfynol CT-324 Surfactant

  1. High-efficiency dynamic surface tension reduction for rapid substrate wetting.

  2. Excellent compatibility with aqueous systems, including low-VOC and high-solids formulations.

  3. Low foaming profile suitable for demanding industrial coating and ink applications.

  4. Stable performance across a broad pH range (pH 2–12) and in the presence of electrolytes.

  5. Non-ionic ethoxylated acetylenic chemistry enabling low migration and improved film integrity.

Typical Applications Of Evonik Surfynol CT-324 Surfactant

  1. Waterborne architectural coatings for enhanced flow, leveling, and substrate wetting.

  2. Industrial maintenance coatings requiring fast wetting on difficult substrates (e.g., plastics, metals).

  3. UV-curable and hybrid inkjet inks to improve drop formation and jetting reliability.

  4. Automotive refinish coatings where low foam and high substrate coverage are critical.

  5. Wood coatings formulated for uniform penetration and reduced surface defects.
