Full surface dust extraction thanks to open net backing

Grit on a net backing enables full surface dust extraction thanks to the open backing structure. For the first time, this dust extraction ensures a virtually dust free work environment in which one’s health is protected, process reliability is improved and the lifetime of the abrasive is increased.

Conventional: Closed coating

The conventional electrostatic grit coating method is closed coating.

New: open coating

Open coating from sia Abrasives has optimised grit positioning to provide an improved removal rate with minimal clogging.
Advantages:

  • Minimal clogging due to open coating technology and optimised stearate composition (zinc-free)
  • Maximum removal rate
  • Longest lifetime
  • Lower abrasive consumption
  • Higher efficiency
  • Lower costs
