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

Soap greases melt, polymer viscosifiers degrade, waxes liquefy — organoclay's inorganic clay platelet network is thermally stable to 200°C. Grease drop point exceeds 260°C; HTHP drilling fluid rheology maintained at 180°C downhole.

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
