Multiwet BD Wetting Agent

Multiwet BD Wetting Agent is a high-performance silicone-based surfactant from the Multiwet series by BYK-Chemie. It rapidly reduces surface tension in aqueous systems, enabling superior substrate wetting and leveling in coatings, inks, and agrochemical formulations. Designed for low-foam, high-stability performance, it enhances spreading without compromising viscosity or compatibility.

Features Of Multiwet BD Wetting Agent

  1. Ultra-low surface tension (<25 mN/m at 0.1% aqueous solution) for rapid substrate penetration and uniform wetting.

  2. Excellent compatibility with anionic, nonionic, and cationic formulations across wide pH range (pH 4–12).

  3. Non-foaming performance under high-shear mixing and spray application conditions.

  4. Biodegradable surfactant system compliant with OECD 301B standards.

  5. Stable in hard water (up to 500 ppm CaCO₃) without precipitation or phase separation.

Typical Applications Of Multiwet BD Wetting Agent

  1. Agricultural adjuvants for herbicides, insecticides, and foliar fertilizers.

  2. Industrial cleaning concentrates for metal, concrete, and textile substrates.

  3. Water-based coatings and architectural paints requiring defect-free film formation.

  4. Agrochemical seed treatment formulations to ensure even active ingredient distribution.

  5. Printing ink systems where substrate wettability and pigment dispersion stability are critical.
