Organoclay Solutions by Performance Problem

Anti-Sagging Agent

Wet paint film flows down vertical surfaces before curing — organoclay builds a thixotropic yield point of 3–15 Pa that holds the film in position. Network collapses instantly under brush/spray shear, then recovers in 5–30 seconds after application.

High Temperature Stability

Evaluate organoclay in grease, coatings and drilling fluids using the heat exposure and acceptance tests that matter to each complete formulation.

Adsorption & Water Treatment

Organoclay removes petroleum hydrocarbons, BTEX, PAHs, chlorinated solvents, and heavy metals from industrial wastewater and contaminated groundwater — through hydrophobic partitioning at 1–5 g/L dosage. Effective where activated carbon is blocked by emulsified oil.

Anti-Settling Agent

Pigments and fillers sinking to the bottom of paint, ink, or coating containers during storage — forming hard cake that cannot be re-dispersed. Organoclay builds a thixotropic platelet gel network that suspends dense particles (TiO₂, BaSO₄, Fe₂O₃) at rest for 12+ months, while collapsing instantly under stirring shear.

• Prevents hard sediment in solvent-based paints, inks, and primers
• Effective at 0.2–1.5 wt% — lowest dosage of any anti-settling class
• Dual function: also prevents sag on applied vertical surfaces
• Thermally stable — maintains anti-settling performance at 50–80°C storage

Viscosity Control

Industrial formulations need high viscosity at rest (anti-settling, anti-sagging, cutting transport) and low viscosity under shear (easy pumping, spraying, application). Organoclay provides both simultaneously through thixotropic gel behavior — no other single additive class achieves this combination at 0.2–2.0 wt% dosage.

• Thixotropic index 3.0–8.0 in solvent-based coatings
• Yield point 10–25 Pa in oil-based drilling fluids for cutting transport
• NLGI 1–3 grease consistency at 8–15 wt% in base oil
• Thermally stable viscosity profile from −20°C to 180°C

Fluid Loss Control in Oil-Based Mud

Measure filtration and filter-cake response in a matched oil-based mud trial. Organoclay is primarily a rheology additive; any contribution to fluid-loss control must be verified in the complete formulation.
