Features Of Evonik Surfynol PSA-216 Acetylenic Diol Surfactant

  1. Highly effective dynamic surface tension reduction for rapid substrate wetting and leveling.

  2. Low foam profile, suitable for high-shear and recirculating coating systems.

  3. Excellent compatibility with waterborne acrylics, polyurethanes, and epoxy dispersions.

  4. Stable performance across a broad pH range (pH 4–10) without hydrolysis risk.

  5. Non-ionic character ensures low sensitivity to electrolytes and hardness ions.

Typical Applications Of Evonik Surfynol PSA-216 Acetylenic Diol Surfactant

  1. Waterborne industrial coatings (e.g., coil, can, and automotive OEM primers).

  2. High-performance architectural paints requiring fast flow and defect-free film formation.

  3. UV-curable and hybrid resin systems where low volatility and thermal stability are critical.

  4. Adhesives and sealants formulations requiring balanced wetting and deaeration.

  5. Inkjet inks and functional printing fluids demanding precise droplet control and nozzle stability.
