Key benefits
1. Lower viscosity build‑up compared to standard organoclays; achieves anti‑settling & anti‑sagging without over‑thickening finished formulations.
2. Gradual thixotropic recovery, balancing anti‑sagging and levelling behaviour for better topcoat gloss retention.
3. Good performance in low‑to‑medium‑polar solvent systems with alkyd, polyurethane and chlorinated rubber resins.
4. Reduce pigment sedimentation and phase separation during storage.
5. Well‑suited for spray‑applied topcoats, avoiding excessively high spray viscosity.
Main application fields
Core applications: Solvent‑borne industrial topcoats, decorative paints, aerosol spray paints, general‑purpose printing inks
Suitable for: Industrial primers, anti‑corrosive topcoats, plastisols
Not suitable for: Formulations dominated by strong high‑polar ketones‑esters, 100 % water‑based systems, food‑contact articles
