Elementis BENTONE SD‑1 Easy‑disperse Organoclay, No Pre‑gel Required, Rheology Additive for Alkyd, Anti‑corrosive & Road‑marking Paints

Full name & product positioning Full product name: BENTONE SD‑1 Easy‑disperse Organo‑modified Clay. Next‑generation rheology additive without pre‑gel or external activator. Designed for non‑polar to medium‑polar aliphatic / aromatic solvents. Simplify production workflow and allow direct charging. Key technical parameters Chemical composition Organo‑modified hectorite Appearance Pale off‑white fine powder Density 1.47 g/cm³ Moisture content ≤2.5 % Loss on ignition 33‑37 % 325‑mesh residue ＜ 120 ppm Physical form Fine powder Standard package 25 kg / bag   CAS No. 1302‑78‑9 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
