Features Of Evonik Surfynol CT-136 Surfactant

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

  2. Excellent compatibility with water-based acrylic, epoxy, and polyurethane systems.

  3. Low foaming profile suitable for high-shear industrial coating and ink processes.

  4. Good hydrolytic stability across a broad pH range (pH 4–10).

  5. Non-ionic ethylene oxide/propylene oxide copolymer structure enabling low VOC impact.

Typical Applications Of Evonik Surfynol CT-136 Surfactant

  1. Waterborne architectural coatings for improved flow and leveling.

  2. Industrial maintenance coatings requiring fast substrate penetration on low-energy surfaces.

  3. UV-curable and hybrid inks where low surface tension aids pigment dispersion.

  4. Automotive refinish clearcoats to minimize cratering and enhance gloss uniformity.

  5. Adhesives and sealants formulations needing balanced wetting without foam generation.
