Advantages compared to other cleaners:

  • Due to its wide process window ZESTRON® SW reliably removes solder pastes from the stencil underside.
  • Dries fast and residue-free on stencils after dry wipe.
  • Good delineation stability and reduced solder balling (see Technical Information 4)
  • Unlike Isopropanol (flash point: 12°C/54°F) ZESTRON® SW (flash point: 67°C/153°F) dramatically increases operational safety while operating stencil printing equipment.
  • ZESTRON® SW is based on non-halogen, organic solvents.
  • ZESTRON® SW is biodegradable.
  • Reduces the amount of cleaning cycles.
