Key benefits
1. No pre‑gel and no extra activator required; rheology develops under low shear to shorten production cycles.
2. Good anti‑settling and anti‑sagging performance: gel forms at rest while viscosity drops under shear for smooth application.
3. Excellent performance in xylene, 200# solvent oil and other aliphatic / aromatic solvents.
4. Consistent batch‑to‑batch quality for large‑scale manufacturing.
5. Can be added either at grinding stage or post‑grind for rheology adjustment.
Main application fields
Core applications: Alkyd paints, high‑build anti‑corrosive coatings, road‑marking paints, bituminous paints, industrial primers
Suitable for: Wood stains, general printing inks, DIY decorative coatings
Not suitable for: Formulations dominated by strong‑polar ketones & esters, food‑contact articles
