BENTOCOL 400
It is a particular type of Bentonite with high content of montmorillonite.

BENTOCOL 400 is well calibrated in its characteristics:

High perrformance in a wet system, which allows the use of lower quantities of bentonite still assuring high quality moulds and high permeability.

Lower strenght in a dry system, which allows a better knock-out.

High reclaiming properties, which allows a low fines content and gives the possibility of working at the lowest grade of moisture.

High wet tensile strenght which allows both to fight sand inclusion damages and produce high thickness castings

BENTOCOL 500
BENTOCOL 500 is a special sodium bentonite, particularly suitable for the preparation of synthetic molding sands and above all it is suitable for the manufacture of castings in steel and special cast-irons.
