Quaternary ammonium-modified organoclay for naphthenic oils, paraffin-based mineral oils, and synthetic lubricating systems. High thickening efficiency, rust protection, and thermal stability. No pre-gel required. For lubricating grease and industrial coatings.
CP-2143 is a quaternary ammonium-modified organoclay engineered specifically for naphthenic oil, paraffin-based mineral oil, and synthetic lubricating systems. The surface modification is optimized for the polarity and viscosity characteristics of these base stocks — providing outstanding thickening efficiency, rust protection, and thermal stability without the pre-gel step required by some conventional organoclay grease thickeners. CP-2143 simplifies grease production while delivering consistent NLGI grade and high-temperature performance.

Performance Characteristics
High thickening efficiency in naphthenic/paraffinic mineral oils — optimized surface modification for less-polar mineral oil base stocks
Excellent rust protection — clay platelet barrier network contributes corrosion resistance to bearing and equipment surfaces
High temperature tolerance — clay platelet network thermally stable; maintains grease consistency through service temperature cycles
No pre-gel required — direct addition to base oil with standard mixing; simplifies production vs conventional grease organoclay
No polar activator needed — eliminates activator handling, VOC contribution, and sequencing complexity
Post-correction capability — consistency adjustable after production
Superior system performance and long-term consistency — stable NLGI grade over storage and temperature cycling

CP-2143 vs CP-250A Selection: Use CP-2143 for naphthenic and paraffinic mineral oil base greases — the most common industrial equipment grease base stocks. Use CP-250A for synthetic greases (PAO, polyester, diester, vegetable oil) where higher organic modifier content matches the higher polarity of ester-type base oils. Both achieve NLGI 1–3 consistency at 7–10 wt% with colloid mill processing and drop points exceeding 260°C.
Grease Production Procedure
Add CP-2143 to base oil at 7–10 wt% of total formulation while stirring
No pre-gel or polar activator required
Add other additives (rust inhibitor, antioxidant, EP additives)
High-speed dispersion for 25–30 minutes
Pass through colloid mill and homogenizer — critical for smooth, consistent grease texture
Deaerate, filter, package
Frequently Asked Questions
What base oils is CP-2143 designed for?
CP-2143 is designed for naphthenic oils, paraffin-based mineral oils, and synthetic lubricating systems. Formulated for the polarity and viscosity of naphthenic and paraffinic base stocks — widely used in industrial equipment greases, bearing greases, and gear lubricants. Also suitable for synthetic systems including diester and polyester base oils.
Does CP-2143 provide rust protection?
Yes. CP-2143's surface chemistry contributes to rust protection through a moisture-barrier effect from the organoclay platelet network in the grease structure. This may reduce the required dosage of separate rust inhibitor additives in some formulations — verify through corrosion testing (ASTM D1743, D6138) before modifying rust inhibitor levels.
How does CP-2143 differ from CP-250A for grease applications?
CP-2143 is optimized for naphthenic and paraffinic mineral oils (less polar). CP-250A (LOI 34–36%) is optimized for synthetic oils — polyester, diester, PAO, vegetable — where higher modifier content matches ester polarity. Use CP-2143 for mineral oil base greases; use CP-250A for synthetic base greases. Both use 7–10 wt% loading with colloid mill processing and achieve drop points >260°C.
