CP-EDS is a kind of organo clay rheological additive. It is used in systems of medium polarity and high polarity system. CP-EDS is suitable for Aromatic solvent system and no-solvent inks, sealant and adhesive..
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 34%-37%
Bulk density 0.35~0.45g/cm3
Fineness (<74μm, %) ≥95%
Dispersion fineness (μm) ≤10
CP-EDS is used in the following applications:
CP-EDS When it is used in grease, suitable polar activators are acetone, 95% ethanole, 95% methanol, dipropyl carbonate. Procedures are suggested as below：
1.Heat the solvent to 60～70℃。
2. Add CP-EDS (7%-10% in weight of total formulation) under agitation.
3. Add polar activator (3% of in weight of total formulation) and other additives, mix at high speed for 25-30 minutes.
4. Pump it to pass through gel grinder or homogenizer.
5. Air driving, filtering, and packing.
In other application, no need to heat the solvent, but pre-gel procedure is necessary.
Commonly addition level is 0.2%-2%.
