TopTec – technology for perfect surfaces
The new generation of coating technology uses an open coating system and provides improved positioning of the abrasive grits and optimised stearate composition (zinc-free). Advantage: works over 20% faster with minimal clogging and the longest lifetime.
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
