Product Description

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.
