Features Of Solvay Rhodoline 990 Molecular Defoamer Surfactant

  1. Highly effective molecular defoaming action in low-viscosity aqueous systems.

  2. Non-silicone, non-ionic formulation ensuring compatibility with sensitive formulations.

  3. Low dosage efficiency—typically effective at 0.05–0.3 wt% in final applications.

  4. Excellent thermal and pH stability across broad processing conditions (pH 4–12, up to 90°C).

  5. Minimal impact on foam stability of downstream processes where controlled foaming is required.

Typical Applications Of Solvay Rhodoline 990 Molecular Defoamer Surfactant

  1. Water-based architectural coatings and industrial paints.

  2. Textile auxiliaries including dyeing and finishing baths.

  3. Agrochemical formulations (e.g., herbicides, fungicides, and adjuvant blends).

  4. Industrial cleaning and metalworking fluids.

  5. Printing inks and pigment dispersion systems.
