Bentonite
A binder and plasticiser used in electrode coatings and foundry applications.
Bentonite is a clay that swells when wetted, and that behaviour is what makes it useful. In an electrode coating it gives the wet mix the plasticity needed to extrude cleanly onto the core wire, then holds the coating together as it dries.
The same swelling and bonding behaviour is what makes bentonite the standard binder in green sand foundry moulding.
