CP-187 Organoclay for Waterborne Coatings

CP-187 is a Camp-Shinning inorganic modified montmorillonite rheology additive developed for waterborne coatings and selected aqueous formulations. It is evaluated where formulators need better pigment suspension, sag resistance, viscosity control and storage stability without moving the formulation to a solventborne organoclay. The grade is intended for coating manufacturers and industrial formulators who can confirm dosage, hydration, pH and order of addition through laboratory trials. The published 0.2–8.0 wt% range is only a broad experimental screening envelope, not a CP-187 technical specification.

What is CP-187 organoclay?

A water-compatible modified montmorillonite grade for building thixotropy, suspension and viscosity in qualified aqueous formulations.

Product	Best for	System type	Activation method	Main benefit	Limitation
CP-187	Waterborne coatings and documented adjacent aqueous formulations	Aqueous / water-based	Confirm hydration and dispersion procedure in the current TDS	Thixotropy, suspension, anti-sag and viscosity control	Not positioned for solventborne systems; final use level requires testing

Which applications is CP-187 suitable for?

Water-based paints and coatings — screen for pigment suspension, anti-sagging and storage stability
Waterborne adhesives and sealants — only after binder and pH compatibility testing
Self-leveling flooring compounds — evaluate flow, leveling and settlement together

Application boundary: Do not use this page to select a solventborne grade or to claim a universal dosage. For the broader family, review the water-based organoclay grades and confirm the current CP-187 TDS.

How should CP-187 be dispersed?

Use the current CP-187 TDS to confirm whether the grade should be pre-hydrated or added directly. Water quality, pH, binder chemistry, mixing energy and the timing of surfactants can all change the result.

Establish a control formulation and record water quality, pH and temperature.
Add CP-187 at the confirmed stage under adequate agitation; avoid assuming a solvent-organoclay activation process.
Allow the specified hydration or maturation time before measuring viscosity, sag and settling.
Run a controlled dosage ladder within the broad laboratory envelope and select the lowest level that meets the complete performance target.

How should the 0.2–8.0% range be interpreted?

The 0.2–8.0 wt% figure is an experimental screening range covering very different aqueous formulations. It is not a guaranteed operating window, a finished-product specification or a default starting dosage. Final use level must come from formulation testing and current technical guidance.

How does CP-187 compare with related CP grades?

Grade	Use when	Selection boundary
CP-187	A waterborne formulation needs a model-specific rheology evaluation	The broad 0.2–8.0% envelope is for screening only
CP-EW	The existing water-based grade data better matches the binder and target	Do not assume identical hydration or dosage
CP-WBS	The current TDS identifies it for the target waterborne formulation	Compare pH, water quality and application data

What should formulators check when results are off target?

Observed issue	Check first	Practical next step
Low viscosity	Water quality, pH, binder compatibility, hydration and addition order	Obtain the current procedure and repeat a controlled dosage ladder
Settling remains	Pigment density, solids loading and maturation time	Compare the control with fully hydrated trials at fixed conditions
Poor leveling or excessive drag	Over-structuring, shear history and the full rheology package	Balance anti-sagging and leveling instead of optimizing one value alone
Batch variation	Lot COA, moisture and actual mixing conditions	Send the formulation and test record to technical support

Frequently asked questions about CP-187

Is CP-187 an organoclay for water-based coatings?

Yes. CP-187 is positioned for waterborne coatings and selected aqueous formulations where thixotropy, suspension, anti-sagging and viscosity control are required.

Is 0.2–8.0% the CP-187 technical dosage specification?

No. It is only a broad experimental screening envelope. The final dosage must be selected through formulation-specific trials and the current TDS.

Can CP-187 be used in solvent-based coatings?

CP-187 is not positioned as the default solventborne grade. Use the solvent-based product family and Product Finder for a suitable model.

Does CP-187 require a polar activator?

A product-specific activation procedure is not established by the published source. Do not copy a solvent-organoclay activator recipe; request the current CP-187 dispersion instructions.

What should be measured during a CP-187 trial?

Measure low- and high-shear viscosity, sag resistance, leveling, pigment settling, storage stability and any binder-specific properties under fixed test conditions.

Can CP-187 be used in waterborne adhesives or flooring?

These are screening applications only. Binder compatibility, pH, hydration, flow and final mechanical properties must be verified before scale-up.

Which documents are available for CP-187?

Request the current TDS, SDS and lot COA from Camp-Shinning, together with a sample and formulation review.
