Features Of Wacker NE 4720 Silicone fluid emulsion

  1. Highly stable anionic silicone emulsion with excellent shelf life and freeze-thaw resistance.

  2. Provides superior lubricity and surface slip without compromising adhesion in downstream formulations.

  3. Low foaming profile, enabling compatibility with high-shear mixing and industrial coating processes.

  4. Easily incorporated into aqueous systems without pre-dilution or surfactant adjustment.

  5. Non-yellowing and chemically inert under neutral to mildly alkaline conditions (pH 6–9).

Typical Applications Of Wacker NE 4720 Silicone fluid emulsion

  1. Textile finishing for soft hand feel, wrinkle resistance, and anti-static performance.

  2. Personal care formulations including shampoos, conditioners, and skin lotions for conditioning and spreadability.

  3. Water-based paints and architectural coatings to enhance leveling, gloss uniformity, and substrate wetting.

  4. Paper and board coatings for improved release, surface smoothness, and ink receptivity.

  5. Industrial metalworking fluids as a defoaming and boundary lubrication additive.
