Features Of DOW VORASURF SZ-1142 Fluid

  1. High-performance silicone-based surfactant offering exceptional substrate wetting and leveling in demanding coating systems.

  2. Low dynamic surface tension enables rapid defect suppression, including craters, orange peel, and pinholes.

  3. Excellent compatibility with waterborne, solventborne, and high-solids resin systems, including acrylics, polyurethanes, and epoxies.

  4. Non-foaming formulation minimizes air entrapment and supports efficient deaeration without compromising surface activity.

  5. Stable across a broad pH range (pH 4–12), ensuring robust performance in diverse formulation environments.

Typical Applications Of DOW VORASURF SZ-1142 Fluid

  1. Automotive OEM and refinish coatings requiring high-gloss, defect-free finishes.

  2. Industrial maintenance coatings for metal and concrete substrates.

  3. Architectural waterborne interior and exterior wall paints.

  4. Wood coatings, including stains and clear topcoats, where uniform flow and substrate coverage are critical.

  5. UV-curable and hybrid curing systems seeking improved wetting without migration issues.
