Features Of DOW XIAMETER MEM-3422 Emulsion

  1. High-solids, anionic methyl-hydrogen silicone emulsion offering excellent hydrophobicity and surface slip.

  2. Stable across a broad pH range (pH 4–9), enabling compatibility with many water-based formulations.

  3. Low viscosity and easy dispersibility in aqueous systems without requiring high-shear mixing.

  4. Provides durable water repellency and reduced surface friction on porous and non-porous substrates.

  5. Free of APEOs (alkylphenol ethoxylates) and compliant with major global regulatory frameworks for industrial use.

Typical Applications Of DOW XIAMETER MEM-3422 Emulsion

  1. Textile finishing for durable water and stain resistance in apparel and technical fabrics.

  2. Concrete and masonry sealers to enhance water repellency while maintaining vapor permeability.

  3. Leather conditioning agents for softness, water resistance, and improved grain appearance.

  4. Coating additives for architectural paints and industrial coatings to reduce surface tension and improve leveling.

  5. Nonwoven fabric treatment for hygiene products, providing hydrophobic barrier properties without compromising breathability.
