SPECJAL bentonite

Specjal Bentonite is a casting bentonite enhanced with sodium cations (i.e. activated) to radically improve performance. It is used in founding as a binder for moulding sands and core sands.

The advantages of using the activated Specjal Bentonite:

  • Improved resistance of moulding sands to compression and tearing;
  • Improved resistance to high temperature (refractory performance);
  • Higher swell factor, i.e. hydration of bentonite;
  • Better flowing of moulding sands.

Application:
Specjal Bentonite is intended for processing with automatic moulding lines and moulding machines. It is widely used for casting of iron, steel and non-ferrous metals.
