Smaltiriva RELEASE Coating “PC” and “SR” Systems

  • Easy-to clean surface
  • Release coating must be able to keep clean rolls from stickies and convey them to a collection point
  • Release coating must be abrasion and abuse resistant to felt
  • Release coating must not damage felt

 Release coating systems on:

  • Dryers Dry-end - Felt guide rolls - Paper guide rolls

 Traction coating systems on:

  • Pope rolls - Winder rolls - Cutter rolls

 Special coating systems for:

  • Steam boxes - Suction fans - Cleaner pumps (experimental stage) - Vacuum pumps (experimental stage)

All coatings are applied by specialist on site directly on the papermachine.
