Bentone® (Adhesive ingredients)

Bentone® by Elementis is a range of organically modified bentonite and hectorite clay-based organoclays used as rheological additives, thickeners, and anti-settling agents in solvent-borne adhesive and sealant formulations. The portfolio includes conventional grades requiring polar activation and pre-gelling, covering aliphatic, aromatic, and mixed solvent systems across a broad polarity range.

Key benefits of Bentone® brand include:

Imparts high low-shear viscosity and strong thixotropic behavior for effective sag and flow control.
Delivers excellent storage stability and elimination of sedimentation in formulated systems.
Hectorite-based grades provide superior purity and consistent rheological performance versus bentonite alternatives.
Optimizes workability and application properties through controlled viscosity build.
Compatible with a broad range of solvent polarities via selection of appropriate quaternary ammonium-modified clay grades.
