Products Specifications:
BK-045 Paper Industry grade Bentonite
BK-045 is Na-Bentonite, It presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. It is used to modified starch adhesive, increase the solid content, reduce moisture; can plug and fill the paper fiber gap; reduce moisture penetration, increase the adhesive stick early And the speed of drying, is the ideal fast-drying agent. It also used in “Cation polyacrylamide / bentonite retention system”.
