Key benefits
1. High gel strength providing excellent suspension and anti‑settling for high‑build and heavily‑filled coatings.
2. Stable rheology performance in mixed‑solvent blends; gel structure resists solvent‑induced breakdown.
3. Strong anti‑sagging for thick‑film application and allows higher single‑coat film thickness.
4. Well‑matched with heavy‑duty epoxy, vinyl and chlorinated rubber high‑build systems.
5. Improve shelf stability and reduce in‑can water separation and hard sediment formation.
