BENTONE^® AD

BENTONE AD rheological additive is an easily dispersible, highly refined hectorite. BENTONE AD has been developed for water-borne automotive base-coats and general industrial systems. It is particularly suitable for metallic-pigmented paints.

BENTONE AD provides a shear-thinning viscosity, exceptional anti-settling and sag control, across a wide range of application temperatures, without increasing the mid-shear-rate viscosity significantly.

BENTONE AD imparts excellent spraying properties and aluminium pigment alignment. Its controlled particle size gives a smooth film-appearance and does not impair gloss.
