CP-40 is an organic modified bentonite clay.
It can be widely in solvents from law polarity to medium-high polarity.

Typical properties
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105C, 2hr) ≤ 3.5%
Viscosity, mPa. S 4500-7500
Loss on ignition max, %(1000C) 28.5%-32%
Bulk density 0.48-0.5 g/cm3
Fineness (<74μm, %) ≥ 98%

Application:
1 200# solvent oil, coal tar or aromatic hydrocarbon solvents
2 Inks
3 Grease
4 Sealant
5 Paint, bituminous coating

Using:
No heating is needed in application.
Dispersing under high shear and require a polar activator for best efficiency.
Adding levels are typically in 0.2%~2.0%.
