Thixotropic agent CP-257 is a new style of organo clay rheological additive made from bentonite. The thixotropic additive is used in solvent and resin systems covering low polarity to high polarity range.
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 40%-45%
Bulk density 0.40~0.60g/cm3
Fineness (<74μm, %) ≥98%
Dispersion fineness (μm) ≤8
Thixotropic agent CP-257 is used in the following applications:
Thixotropic agent can be added directly in powder under high shear condition. Addition level is commonly 0.1%~1.0% (7%-10% in greases) of total formulation by weight. In low and medium polarity solvents, polar activator is required to achieve better performance.
The addition procedure is suggested as below.
If to make pre-gel, better efficiency can be achieved. Addition level in pre-gel is 8%-10% of total pre-gel in weight.
Pre-gel procedure is as below.
Polar activator is suggested to be ethanol/water (95/5)or acetone/water (95/5). Dosage of polar activator is about 10%-35% of CP-257 by weight.
Note: The suggested addition level of our organoclay and polar activator is based on our lab testing. Exact dosage for detail formulation should be based on user’s testing.
