CP-MPZ Organoclay for Printing Ink

CP-MPZ is a Camp-Shinning organophilic montmorillonite rheology additive positioned for printing inks. It is evaluated where formulators need controlled body, pigment suspension, thixotropic flow and viscosity stability in medium- to high-polarity or mixed-solvent systems, including selected UV acrylate inks after compatibility testing. CP-MPZ can be added as powder under high shear, and the same-company source states that a polar activator is required for better performance. Ink manufacturers should determine the final level by press-relevant flow, fineness, cure, adhesion and storage testing.

What is CP-MPZ organoclay?

An ink-focused organophilic montmorillonite grade for thixotropic flow, viscosity control and pigment suspension in qualified solvent, mixed-polarity and selected UV acrylate systems.

Product	Best for	System type	Activation method	Main benefit	Limitation
CP-MPZ	Medium/high-polarity, mixed-solvent and selected UV inks	Qualified solvent/resin and acrylate systems	Direct powder under high shear; polar activator required for better performance	Thixotropy, viscosity and pigment suspension	Water-based and regulated-use suitability is not established

Which applications is CP-MPZ suitable for?

Printing ink — primary application for pigment suspension, body and flow control
Paint and coatings — secondary rheology screening only when the polarity and resin package match
Lubricating grease — not the primary page intent; use only when current product data support the base oil

Application boundary: This page does not establish CP-MPZ for water-based inks, food-contact use or every UV formulation. Cure, adhesion, gloss, color strength and storage stability must be checked in the actual ink.

What are the technical parameters of CP-MPZ?

Parameter	Published value	Scope / note
Composition	Organic derivative of montmorillonite clay	Same-company CP-MPZ source
Appearance	Fine powder, light yellow	Visual description
Moisture	≤3.5%	105°C for 2 hours
Loss on ignition	31–34%	1,000°C
Fineness	≥98% passing 74 μm	Sieve reference
General addition	0.1–1.0 wt%	Dedicated product-source guidance; optimize in actual ink
UV-ink reference	0.3–1.0 wt%	Application-level range; validate cure and adhesion
Dispersion	Direct powder addition under high shear	Dedicated product-source guidance
Activation	Polar activator required for better performance	Select type and ratio from current TDS and vehicle testing
Shelf life	2 years	Store cool, dry and ventilated

How should CP-MPZ be dispersed in printing ink?

The dedicated product source supports direct powder addition under high shear and states that a polar activator is required for better performance. Use the current TDS to select the activator and exact sequence for the ink vehicle.

Charge the validated solvent, resin, oil or monomer portion.
Add CP-MPZ before grinding while maintaining agitation.
Apply high shear for at least ten minutes or until the confirmed dispersion endpoint is reached.
Add the approved polar activator at the validated stage and ratio.
Complete pigment grinding and let-down, then test fineness, viscosity, thixotropy, print flow and storage.

How should CP-MPZ dosage be selected?

Use 0.1–1.0 wt% as the dedicated general formulation range and 0.3–1.0 wt% as the current application reference for selected UV acrylate inks. These are trial ranges, not a guarantee of press performance.

How does CP-MPZ compare with related CP grades?

Grade	Use when	Selection boundary
CP-MPZ	The search and formulation intent is ink rheology in qualified medium/high or mixed-polarity systems	Requires high shear and suitable polar activation
CP-EDS	Fine-particle or ketone/ester compatibility is the stronger requirement	Different fineness and process data
CP-40	A conventional oil-based or aromatic ink route is being screened	Its primary page also covers coatings and grease
CP-388	The current TDS identifies the widest polarity range as the main requirement	Compare activation and final ink properties

What should formulators check when results are off target?

Observed issue	Check first	Practical next step
Pigment settling	Dispersion, polarity match and treatment level	Run a CP-MPZ ladder at fixed shear and maturation conditions
Ink too thick at press shear	Over-treatment and grade compatibility	Measure low- and high-shear viscosity before adjustment
Poor leveling or gloss	Recovery rate, fineness and let-down order	Review dispersion endpoint and balance body against leveling
UV cure or adhesion changes	Monomer, pigment surface and photoinitiator interactions	Complete cure, adhesion and storage tests before scale-up

Frequently asked questions about CP-MPZ

What is CP-MPZ organoclay used for?

CP-MPZ is used to control thixotropy, viscosity, pigment suspension and body in qualified printing-ink systems.

What is the general CP-MPZ addition range?

The dedicated product source gives 0.1–1.0 wt% of the total formulation as general guidance. Final dosage must be selected in the actual ink.

Can CP-MPZ be used in UV-curable ink?

Selected UV acrylate inks can be screened at the application reference of 0.3–1.0 wt%, followed by cure, adhesion, gloss and storage testing.

Does CP-MPZ require a polar activator?

The same-company source states that a polar activator is required for better performance. Use the current TDS to select the type, ratio and addition stage.

When should CP-MPZ be added?

The source supports direct powder addition under high shear, normally before grinding when the formulation procedure confirms that sequence.

Is CP-MPZ suitable for water-based ink?

Water-based suitability is not established by the current source. Use a water-compatible grade and application-specific data instead.

What tests should be run before scale-up?

Check fineness, low- and high-shear viscosity, thixotropic recovery, pigment settling, print flow, gloss, color strength, storage stability and, for UV systems, cure and adhesion.

How does CP-MPZ differ from CP-EDS?

CP-MPZ has an ink-focused positioning and its own activation and dosage guidance. CP-EDS is selected where fine-particle and medium/high-polarity requirements lead the decision.
