Features Of DOWSIL HMW 2220 Silicone Emulsion

  1. High-molecular-weight polydimethylsiloxane (PDMS) emulsion offering exceptional film-forming capability and surface lubricity.

  2. Stable, anionic emulsion with excellent compatibility in water-based systems including acrylics, vinyl acetates, and cellulose derivatives.

  3. Low surface tension and superior spreading behavior on diverse substrates, enhancing wetting and leveling performance.

  4. Non-yellowing and thermally stable up to 150 °C, supporting durability in curing and drying processes.

  5. Designed for low-VOC formulations with no added APEOs or heavy metals, meeting key regulatory expectations for industrial coatings and adhesives.

Typical Applications Of DOWSIL HMW 2220 Silicone Emulsion

  1. Release coatings for paper, film, and foil substrates in converting operations.

  2. Surface modification additive in architectural and industrial waterborne paints for slip, mar resistance, and substrate wetting.

  3. Performance enhancer in pressure-sensitive adhesives (PSAs) to improve peel adhesion balance and clean release.

  4. Softening and anti-blocking agent in textile finishing formulations for synthetic and blended fabrics.

  5. Processing aid in nonwovens manufacturing to reduce fiber friction and improve web handling.
