Organoclay Rheological Additive CP-250

CP-250

CP-250 is a kind of purified and modified organoclay rheological additive, designed especially for using in low to middle solvent system ink, such as planographic printing ink, New ink, gravure printing ink etc.. It has high gelling efficiency, fine thixotropy and perfect anti-settling.

Composition                               Organic derivative of a montmorillonite clay

Appearance                                Fine powder, light yellow

Moisture content (105℃,2hr)      ≤3.5%

Loss on ignition (1000℃)            35%-38%

Bulk density                                42g/cm3

Fineness (<74μm, %)                 ≥98%

CP-250 is used in the following applications:

Ÿ   Inks

Ÿ   Wood coating

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..
