SEPIOLITE thickener, anti-settling agent 1kg

Sepiolite is a soft white mineral. Sepiolite is opaque and of white, gray or cream color, breaking with a concoidal or fine earthy fracture, and occasionally fibrous in texture.

Sepiolite is a hydrous magnesium silicate with the formula H4Mg2Si3O10.

Sepiolite is a colloidal, asbestos-free thixotrope, anti-settling agent and thickener for watery suspension systems, high and medium polar solvents, for solvent-free and solvent-less resin and polymer systems.

Sepiolite is a natural product (asbestos-free), 60 % sepiolite, 40 % of other types of clay.
