The search for white fillers that can replace and compete with titanium dioxide have favoured the amorphous aluminium silicates. Aluminium and sodium silicate is a white-coloured amorphous solid, obtained by the reaction of chemical precipitation between a sodium silicate and an aluminium salt in aqueous medium. It is a filler with many different applications, and it is used as a raw material in sectors such as the manufacture of paints, printing inks, the rubber or the paper sector.

Products

SODASIL^® P95 is the trade name of the amorphous sodium and aluminium silicate marketed by IQE in the paint sector. It is used as a white pigment in paints, printing inks and paper, where it acts as a partial substitute for titanium dioxide (extender) at the same time as it increases the covering power and brightness both of the paint and of the paper.

SODASIL^® P80 is an aluminium silicate and amorphous sodium commercialised by IQE in the paint industry that grants it a higher effect compared to other aluminium silicates, achieving a 30% reduction in brightness.

EBROSIL^® SA-60 is the amorphous sodium and aluminium silicate manufactured by IQESIL and which is used as a white filler in rubber, with a moderate reinforcing nature. Its application is especially indicated in the preparation of technical rubber pieces via an extrusion or injection moulding process. Both the natural and synthetic rubber blends, which contain EBROSIL^® SA-60 present good processability, even with higher filler levels than the reinforcing silica, as well as good vulcanisation properties. Their slightly alkaline nature permits their use in basic blends.
