BK®-035A
Foundery
Grade Bentonite
It is mainly used as molding sand adhesives in cast iron,cast
steel.It has higher content of montmorillonite,better green strength and hot
strength,higher swelling property and better heat stability compared with
similar domestic products. Using BK®-035A can reduce the dosage of
bentonite and water content of sand system, increase the intensity and
flexibility of molding sand, improve ventilation, apparently improve the quality
of cast,reduce waster.
