Bentobest

Description 

BENTOBEST is a western type high swelling sodium bentonite for foundry use. BENTOBEST is most suitable for precision casting of steel and different alloys. It gives high green, dry and baked strengths of mould as compared to ordinary calcium bentonite. It provides high permeability and thus casting results are remarkably improved and casting defects are reduced.
