Features Of DOW DOWSIL 593 Fluid Silicone Fluid

  1. Low-viscosity, linear polydimethylsiloxane (PDMS) fluid with excellent thermal stability and oxidative resistance.

  2. Non-volatile, non-toxic, and odorless—suitable for applications requiring high purity and regulatory compliance.

  3. Outstanding hydrophobicity and surface slip, providing effective lubrication and release performance.

  4. Compatible with a broad range of elastomers, plastics, and coatings without causing swelling or degradation.

  5. Stable across wide temperature range (−40 °C to +180 °C), maintaining consistent rheological behavior.

Typical Applications Of DOW DOWSIL 593 Fluid Silicone Fluid

  1. Lubricant for precision mechanical components, including optical assemblies and micro-electromechanical systems (MEMS).

  2. Release agent in rubber and silicone molding processes for complex geometries and high-gloss surfaces.

  3. Base fluid in specialty personal care formulations, such as hair conditioners and skin protectants.

  4. Dielectric coolant and damping fluid in electronic potting and sensor applications.

  5. Carrier fluid for active ingredients in industrial coatings and functional additives.
