Specialty Organoclay Grades — Self-Activating, Grease & Cosmetic Applications

Specialty Grade Overview

CP Grade	Key Feature	Primary Application	Activation
CP-180B	Self-activating (pre-coated PC)	High-solid coatings, OBM drilling	None required
CP-992	Self-activating, ultra-fine particle	High-performance oil-based drilling fluids	None required
CP-250A	High yield value, grease-optimized	Lubricating greases	Heat + shear
CP-EW	Water-dispersible modified clay	Waterborne coatings, cosmetics, personal care	Water dispersion

CP-180B — Self-Activating Organoclay

CP-180B has propylene carbonate (PC) pre-coated on the clay surface during manufacturing, eliminating the external polar activator step during dispersion.

Key Takeaway: Add CP-180B directly to the grind phase — no separate activator addition. Achieves thixotropic index ≥ 4.0 at 1 wt% in xylene at 25°C per internal QC protocol.

Ideal for:

High-solid solvent-based coatings where external activator addition is impractical
Oil-based mud (OBM) drilling fluids preferring simplified addition protocol
Formulations where activator cost or compatibility is a concern

CP-992 — High-Performance Drilling Grade (Self-Activating)

CP-992 is an ultra-fine particle self-activating organoclay engineered for demanding oil-based drilling fluid applications. Provides rapid gel build-up and stable rheology across a wide temperature range.

Tested to API 13A Section 14 requirements
Ultra-fine particle for faster dispersion under field conditions
Self-activating: direct addition to OBM base fluid, no activator required

CP-250A — Lubricating Grease Grade

CP-250A is specifically optimized for lubricating grease thickening. Delivers high yield value at 8–15 wt% treat rate on base oil weight and maintains stability at temperatures up to 180°C.

High-temperature industrial greases and open-gear lubricants
Used where clay thickener is specified in grease formulation standards
SGS third-party analysis available for grease industry qualification

CP-EW — Water-Dispersible Organoclay

CP-EW is a specially modified organoclay that disperses in water and aqueous media, providing thixotropy and suspension control in systems where standard solvent-based organoclay is not compatible.

Waterborne paints and architectural coatings
Cosmetics and personal care (rheology modifier, skin feel enhancement)
Water-based adhesives and sealants
