S&B bentonites offer wide-ranging ecological, economic and quality
benefits.
S&B bentonites:
|
|
Hight montmorillonite content |
|
|
Outstanding thermal stability ideally
adapted to the technical requirements of
each individual foundry |
|
|
High specific bonding power. During the
moulding process, the specific technological
properties of these products
really come to bear, enhancing the quality
of the mould as an integral ingredient in
the mix of factors affecting the
moulding process. The most important
features in this regard |
 uniform mould compaction
high mould and edge stability
excellent pattern transfer fidelity
Zero pollution or toxic emissions during mould-making
and casting.
