Evonik Surfynol 104BC Defoamer

Evonik Surfynol 104BC Defoamer is a high-efficiency, silicone-free antifoam agent designed for water-based industrial coatings and inks. It delivers rapid foam suppression and excellent compatibility without affecting gloss or substrate wetting. Ideal for low-surface-tension systems, it ensures stable performance across pH and temperature ranges while maintaining formulation clarity and ease of incorporation.

Features Of Evonik Surfynol 104BC Defoamer

  1. Highly effective silicone-free defoamer for rapid foam knock-down and long-term foam suppression.

  2. Excellent compatibility with water-based systems including acrylic, vinyl acetate, and styrene-butadiene emulsions.

  3. Low dosage requirement — typically effective at 0.05–0.3 wt% active in final formulation.

  4. Non-yellowing and does not impair gloss, clarity, or film integrity in coatings and adhesives.

  5. pH-stable across broad range (pH 4–12), suitable for both acidic and alkaline formulations.

Typical Applications Of Evonik Surfynol 104BC Defoamer

  1. Architectural and industrial waterborne coatings (e.g., interior/exterior paints).

  2. Water-based adhesives and sealants (e.g., PVA, EVA, and SBR formulations).

  3. Textile and leather finishing auxiliaries (e.g., dye baths, padding liquors).

  4. Construction chemicals (e.g., cementitious tile adhesives, grouts, and renders).

  5. Printing inks (flexographic and gravure water-based inks).
