3, Modifying bentonite Using

CP-250 When it is used in ink, no need of polar solvent, heating. It is also added while stirring. The common addition level is 0.2%-2.0% of the total formulation. It depends on the actual test of customers.

Note:With High-speed dispersant of grinding machine, and properly prolong the dispersing time, better gelatin performance can be reached..
