Sillitin N 85 in welding electrodes

Sillitin N 85 is our standard product with balanced profile of properties.

 

  • improved workability
  • very good extrusion properties
  • high specific surface area and pore structure
  • ideal chemical composition through natural combination of silica and kaolinite
  • no unwanted side effects with the binder, such as sodium Silicate (water glass)
  • very good slag flow through uniform shearing
  • welding possible in all positions
