Product details

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

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:
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

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.

Safety:
All safety information is provided in the Material Safety Data Sheets for Zhejiang Camp-Shinning New Material Co.,Ltd.

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.
