Product details

Organoclay CP-40 is an modified bentonite, designed especially for use in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity.

Organoclay Properties

Composition                      Organic derivative of a montmorillonite clay

Appearance                       Fine powder, light yellow

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

Loss on ignition (1000℃)            28%-31%

Bulk density                       0.53g/cm3

Fineness (<74μm, %)               ≥98%

Advantages– Organoclay

  • High gelling efficiency,high viscosity
  • Wide application range, it can be applied in all low, middle and high polarity range
  • Produce reproducible thixotropic consistency over a wide temperature range
  • Imparts particle suspension, preventing hard settling of pigment and fillers
  • Exerts strong film reinforcing action in organic binder systems

Organoclay Application

CP-40 is used in the following applications:

  • Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints
  • Grease
  • Inks
  • Sealant

Using

CP-40 disperses under high shear and requires a polar activator for best  efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of CP-40 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-40 in weight.

Pre-gel is made as below procedure.

  1. Charge solvent to mill
  2. Slowly add CP-40 (6-10% by weight of total pre-gel) to mill under agitation.
  3. Mix at high speed for 5 minutes.
  4. Add polar activator.
  5. Mix at high speed for 5 minutes.

Package

Kraft bag or kraft complex interior with PE or customized

Storage

CP-40 has a shelf life of 2 years, and should be stored in ventilated cool and dry place.
