Silfit Z 91

Technical DataSheet | Supplied by Hoffmann Mineral

SILFIT Z 91 is a natural combination of corpuscular silica and lamellar kaolinite, which has been subjected to a heat treatment. The components and the thermal process lead to a product that offers special performance benefits as functional filler. SILFIT Z 91 enhances the opacity effect of pigments, thus it provides a replacement potential of titanium dioxide up to 20%. In clear coats it achieves good transparency without yellow tint, a slight whitish glazing effect can result depending on formulation principle and loading. The outstanding dispersion behavior enables paint production potentially without grinding, even for low film thickness applications. Imparts relatively low abrasivity, quick drying, weathering resistance, scratch resistance, abrasion resistance, good transparency and matting effect.
