Digesil FS

Digesil® FS Silicone Depolymerizer / Stripping Agent

Description: Digesil FS is more than a solvent; its chemical action shears the silicone/oxygen bond, cutting fluorosilicones into random lengths and rendering it soluble. Digesil FS is primarily used to remove fluorosilicones from electronics parts. Unlike the other Digesil products, Digesil FS is a HAZMAT for shipping due to its lower flashpoint, 133°F.

Benefits of Digesil FS

  • Quickly dissolves cured silicone. Leaves a silicone free surface
  • Chlorinated and fluorinated solvent free
  • Negligible aromatic solvent content
  • Environmentally responsible
  • Low odor for operator comfort
  • Low density for ease of handling
  • Rinses with water or solvent
  • Safe on glass, metal, and most plastic (except nylon)
  • Safe on paint and powder coating
  • Water free


Important: In all cases water must not come in contact with Digesil as this will stop it from working.  Do not dilute or alter the product in any way.

  • Remove heavy accumulations of adhesive or sealants using scrapers or other method.
  • Fill suitable container with Digesil, leaving room for the part.
  • Let soak for 15 – 30 minutes or until residue softens, “lifts” or shows signs of dissolving.  The part can be left to soak as long as it takes to remove all the silicone. This varies based on the type, brand and age of the silicone.
  • Removal: Although water may be used to rinse the product, rinsing with a mild cleaner such as eOx®, also available from RPM Technology, followed by pure water will improve removal of all residues. If you do not want to expose the part to water, then use either methanol or ethanol to clean the part. We do not recommend IPA, as customers have informed us that it does leave a residue.

AVAILABILITY: Digesil FS is available in 500 ml and 5-L containers. This product is made-to-order (MTO) only.
