CP-EDS Organoclay — Fine-Particle Rheology Additive

CP-EDS is a Camp-Shinning fine-particle organoclay rheology additive with published dispersion fineness of 10 μm or less. It is positioned for transparent coatings, selected ketone/ester or UV-related printing inks, and compatible adhesive or sealant systems where coarse particles, haze and unstable suspension are concerns. Formulators should select CP-EDS when particle fineness and medium- to high-polarity compatibility are central requirements. Easy dispersion does not mean universally activator-free, so the current TDS must control activation, order of addition and final dosage.

What is CP-EDS organoclay?

An easy-dispersing, fine-particle organoclay grade for rheology and suspension in qualified medium- to high-polarity solvent systems.

Product	Best for	System type	Activation method	Main benefit	Limitation
CP-EDS	Transparent coatings, selected inks and sealants	Medium- to high-polarity solvent systems	Easy-dispersing; confirm activation in current TDS	≤10 μm dispersion fineness and rheology control	Not automatically self-activating or suitable for every UV system

Which applications is CP-EDS suitable for?

Transparent paints and coatings — where fine dispersion and rheology must be balanced with clarity
Printing ink — ketone/ester and selected UV-related systems after compatibility testing
Adhesives and sealants — selected formulations requiring fine-particle suspension

Application boundary: Do not describe CP-EDS as universally self-activating or suitable for every transparent, UV or high-polarity formulation. Confirm solvent, resin, monomer, pigment and cure compatibility.

What are the technical parameters of CP-EDS?

Parameter	Published value	Scope / note
Loss on ignition	34–37%	1,000°C; confirm current TDS
Moisture	≤3.5%	Grade-table value; confirm CP-EDS COA
Dispersion fineness	≤10 μm	Published grade-table value
Polarity range	Medium to high	Grade-table positioning
Dispersing type	Easy-dispersing	Does not by itself mean activator-free
Transparent-coating reference	0.2–1.0 wt%	Application-level screening range
Ketone/ester ink reference	0.3–0.8 wt%	Application-level screening range
Adhesive/sealant reference	0.5–2.0 wt%	Application-level screening range

How should CP-EDS be dispersed?

Add CP-EDS before grinding when the current formulation and TDS support direct powder incorporation. Provide enough wetting and shear to reach the required fineness; do not infer activator-free processing from the term easy-dispersing.

Charge the validated solvent and resin portion.
Add CP-EDS under agitation before pigments when the formulation procedure calls for it.
Apply high shear for at least the confirmed mixing time; an internal guide uses 2,000–3,000 rpm for 15–20 minutes as a laboratory reference.
Verify fineness, haze, viscosity, suspension and storage stability before let-down or scale-up.

How does CP-EDS compare with related CP grades?

Grade	Use when	Selection boundary
CP-EDS	Fine dispersion and medium/high-polarity compatibility are central	Confirm activation and application compatibility
CP-MPZ	The main intent is UV, mixed-polarity or ink-specific rheology	Its activation and dosage data are different
CP-APA	A self-activating high-polarity grade is confirmed by the current TDS	Fine-particle target and activation route differ
CP-40	A conventional coating or dual coating/grease grade is needed	Not an equivalent fine-particle selection

What should formulators check when results are off target?

Observed issue	Check first	Practical next step
Haze or visible specks	Dispersion endpoint, binder compatibility and required fineness	Measure fineness and review shear before changing dosage
Low suspension	Polarity match and incomplete dispersion	Confirm solvent range and repeat a controlled dosage ladder
Excess viscosity	Treatment, activator and shear history	Measure at a fixed temperature and process history
Unstable ink flow	Ink base, pigment package and press-relevant shear	Test CP-EDS under the actual ink and cure conditions

Frequently asked questions about CP-EDS

What is the published dispersion fineness of CP-EDS?

The current grade table lists dispersion fineness of 10 μm or less. Confirm the test method and current specification in the TDS.

Is CP-EDS suitable for transparent coatings?

It is positioned for transparent coatings where fine dispersion and rheology are required, subject to resin, solvent, haze and gloss testing.

Can CP-EDS be used in printing ink?

Yes, it can be screened in selected ketone/ester and UV-related inks. Press flow, cure, adhesion and storage compatibility must be verified.

Does easy-dispersing mean CP-EDS needs no activator?

No. Easy-dispersing describes processing behavior and should not be treated as a universal activator-free claim. Follow the current TDS.

What dosage should be used for CP-EDS?

Application tables provide screening references of 0.2–1.0% for transparent coatings, 0.3–0.8% for ketone/ester inks and 0.5–2.0% for adhesives or sealants. Final dosage is formulation-specific.

How should CP-EDS be selected against CP-MPZ?

Choose based on the actual polarity, ink or coating target, required fineness and activation route. CP-MPZ has an ink-focused page and separate process data.
