Elementis BENTONE HC Hectorite Clay, Thickening Anti‑settling Anti‑sagging Rheology Additive for Water‑based Coatings & Sealants

Full name & product positioning Full product name: BENTONE HC Modified Hectorite Inorganic Clay. Mineral‑origin rheology additive designed for aqueous systems. Swells in water to form thixotropic colloids for thickening, suspension and anti‑sagging in water‑borne coatings, adhesives and sealants. Key technical parameters Chemical composition Modified lithium magnesium silicate (hectorite) Appearance Grey‑white fine powder Density 2.60 g/cm³ Moisture content ≤10.0 % pH of 2 % aqueous dispersion 9.0‑10.0 325‑mesh residue ＜ 200 ppm Physical form Fine powder Standard package 25 kg / bag CAS No.   123345‑12‑0   Key benefits 1.  Rapid hydration and swelling in water to form translucent‑to‑opaque thixotropic colloids. 2.  Excellent suspension effect to prevent sedimentation of heavy pigments and fillers. 3.  Improve anti‑sagging property of water‑borne coatings and favourably handle workability without deteriorating water resistance of cured films. 4.  Good compatibility with acrylic, water‑borne PU and styrene‑acrylic emulsions. 5.  Inorganic mineral grade, resistant to microbial degradation and viscosity loss caused by biological spoilage. Main application fields Core applications: Water‑borne industrial coatings, water‑based architectural coatings, water‑borne sealants, water‑based adhesives Suitable for: Water‑based colorants, foundry water‑borne coatings, water‑based floor primers Not suitable for: Pure solvent‑based systems, strongly‑acid aggressive formulations, food‑contact articles
