Organoclay Bentonite for Ink
CP 250A Organic Bentonite is a modified rheology additive, it is suitable for use in low and medium polarity ink systems, for example, when you need to have a high gel efficiency, good thixotropy and anti-sedimentation, Bentonite for Ink CP 250A is the best choice, it can be widely used in some gravure printing inks, flatbed printing inks and some new inks.
Solvent Based Organoclay
Bentonite for Ink CP-34 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%-30%
Bulk density 0.53g/cm3
Fineness (<74μm, %) ≥98%
Advantages
- High gelling efficiency
- Light color gel
- 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-34 is used in the following applications:
- Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, polyester paints, Alkyd paints.
- Sealant
- Inks
- Grease
- Unsaturated polyester putty
Using
CP-34 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 40%~50% of CP-34 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-34 in weight.
Pre-gel is made as below procedure.
- Charge solvent to mill
- Slowly add CP-34(6-10% by weight of total pregel) to mill under agitation.
- Mix at high speed for 5 minutes.
- Add polar activator.
- Mix at high speed for 5 minutes.
