results in a combination of a layer-silicate with SiO2. The characteristics of this adsorbent are surface areas > 300 m2/g, pore volume > 0.4 ml/g, high adsorptivity and catalytic properties. Most important applications are special Carbonless Paper- and Inkjet-coatings.
Processing with Organics
can be performed in order to use the layer silicate as carrier for organic functional compounds.
carbonless copying papers, made with acid-modified alumo-silicates
improved formation and retention by the use of alcali-actived alumo-silicates
Processing with Alcali
creates products with extreme swellability in water, gel structure and dispersed surface areas up to 750 m2/g. These grades are used in fibre retention, for thin layer coatings and as rheological additives.
