SILLITIN Z 89

SILLITIN Z 89 and SILLITIN Z 89 puriss are natural combinations of corpuscular silica and lamellar kaolinite. These materials are utilized as functional fillers, particularly in paint and varnish applications. Below are some key details about SILLITIN Z 89:

1. Description:
- SILLITIN Z 89 and SILLITIN Z 89 puriss appear as free-flowing powders.
- They possess specific characteristics such as low residue, low volatile matter content, and moderate electrical conductivity.
- The puriss-grade undergoes a sophisticated manufacturing process, resulting in further reduction of sieving residue and improved dispersion behavior.

2. Applications:
- These fillers find applications in various paint and varnish formulations, including emulsion and silicate paints, industrial paints, wood and foil coatings, anti-corrosion coatings, primers, and electrophoretic paints.
- They exhibit excellent dispersion properties, moderate yield point, and pseudoplasticity, making them suitable for coatings with high solids content and abrasion resistance.
- SILLITIN Z 89 puriss is preferred for applications with extremely high requirements on dispersion behavior and very low coating thickness.

3. Benefits:
- High filling ratio, good pigment dispersion, and low abrasiveness.
- Excellent dispersion behavior, low tendency to settle, and soft sediment.
- Quick drying, weathering resistance, scratch resistance, and good transparency.
- Compliance with standards on basic foodstuffs of the BfR and FDA.

4. Packaging and Shelf Life:
- Available in various packaging options, including paper bags, PE bags, EVA bags, Big Bags, and bulk.
- Shelf life is unlimited if stored properly under dry conditions.

5. Particle Size Distribution and Sedimentation:
- Particle size distribution is measured using the Fraunhofer diffraction spectrum method.
- Sedimentation analysis shows the sedimentation behavior of the fillers in various dispersion mediums.

6. Rheology:
- Rheological properties, including thixotropy, are indicated for different filler concentrations in specific dispersion mediums.

Overall, SILLITIN Z 89 and SILLITIN Z 89 puriss offer a range of benefits and are well-suited for various paint and varnish applications, providing specific advantages such as excellent dispersion, high filling ratio, and abrasion resistance.
