CP-VZ Organoclay for Resin-Based Coatings

CP-VZ is a Camp-Shinning self-activating organoclay for resin-containing formulations based on polyester, alkyd, acrylic, epoxy or polyurethane. It is designed for direct powder incorporation where formulators need viscosity control, thixotropic recovery, pigment suspension and anti-sagging without making a conventional pre-gel. Published dispersion fineness is 20 μm or less, and the confirmed dosage range for this page is 0.3–1.2 wt%. Coating, adhesive, sealant and ink formulators must still validate the resin, solvent, shear and final application properties.

What is CP-VZ organoclay?

A self-activating organophilic clay for viscosity, suspension and anti-sagging in qualified polyester, alkyd, acrylic, epoxy and polyurethane resin systems.

Product	Best for	System type	Activation method	Main benefit	Limitation
CP-VZ	Polyester, alkyd, acrylic, epoxy and PU resin systems	Low- to medium-high-polarity resin-containing systems	Self-activating direct powder route	Viscosity control, ≤20 μm dispersion and post-correction flexibility	Not a universal substitute for ≤10 μm or every solvent-polarity requirement

Which applications is CP-VZ suitable for?

Resin-based paints and coatings — polyester, alkyd, acrylic, epoxy and PU formulations
Adhesives and sealants — qualified resin systems requiring suspension and body
Printing ink — secondary screening where the resin and solvent package match CP-VZ data

Application boundary: Do not use CP-VZ as a universal replacement for ultra-fine grades, waterborne organoclay or every solvent polarity. The single dosage range on this page is 0.3–1.2 wt%.

Confirmed dosage range	0.3–1.2 wt%	Use this single range and determine the final level by resin-system testing

How should CP-VZ be incorporated?

CP-VZ is self-activating and is normally incorporated as powder before grinding. Use 0.3–1.2 wt% as the confirmed page range and select the final level through a controlled resin-system trial.

Charge the validated solvent and resin portion.
Add CP-VZ as powder under agitation before grinding.
Apply adequate high shear until the confirmed dispersion endpoint is reached.
Complete pigment grinding and let-down in the validated order.
Measure viscosity at fixed shear and temperature, then check sag, leveling, fineness and storage stability.

Can CP-VZ be used for post-addition viscosity correction?

CP-VZ may be evaluated for post-addition correction because of its self-activating route, but the correction sequence and finishing shear must be tested on a controlled small batch to avoid specks or incomplete wetting.

How does CP-VZ compare with related CP grades?

Grade	Use when	Selection boundary
CP-VZ	A self-activating grade is needed for polyester, alkyd, acrylic, epoxy or PU systems	Published dispersion fineness is ≤20 μm; dosage is 0.3–1.2 wt%
CP-APA	The current TDS confirms a self-activating high-polarity ketone/ester focus	Different resin and polarity window
CP-EZ	An ultra-fine ≤10 μm target is required	Finer target may require a different processing and cost choice
CP-34	Strong conventional gel development in aromatic or selected coating systems is required	Uses the applicable polar-activation procedure

What should formulators check when results are off target?

Observed issue	Check first	Practical next step
Low viscosity or weak suspension	Resin/solvent match, addition stage, shear and treatment level	Repeat a controlled ladder within 0.3–1.2 wt%
Sagging remains	Film build, pigment/filler loading and recovery	Compare sag and leveling at fixed film thickness
Haze or particles	Dispersion endpoint and clarity target	Measure fineness and compare a finer grade only when required
Excess viscosity or poor leveling	Over-treatment and shear history	Recheck dosage and fixed-condition viscosity
Post-correction specks	Wetting and finishing shear	Review the correction sequence in a small controlled batch

Frequently asked questions about CP-VZ

What resin systems is CP-VZ designed for?

CP-VZ is positioned for qualified polyester, alkyd, acrylic, epoxy and polyurethane resin systems across low- to medium-high-polarity environments.

What is the confirmed CP-VZ dosage range?

The confirmed range used consistently on this page is 0.3–1.2 wt% of the total formulation. Final level must be selected by resin-system testing.

Does CP-VZ require a polar activator?

CP-VZ is self-activating for direct powder incorporation. Process optimization is still required, and any optional activator route should only be used when the current TDS and trial support it.

What is the dispersion fineness of CP-VZ?

The published value is 20 μm or less. Confirm the current test method and lot specification in the TDS and COA.

Can CP-VZ be added after let-down for viscosity correction?

It can be evaluated for post-addition correction, but wetting and finishing shear must be validated on a small batch to prevent specks.

When should a finer grade be selected instead of CP-VZ?

Consider a grade with a 10 μm or finer target when high clarity, very smooth texture or a stricter fineness requirement is central to the product specification.
