Silfit
Our premium Silfit Z 91 is derived from Sillitin Z 86 through a specialized thermal process. During this process, the crystal water in the kaolinite content is removed, resulting in the formation of new, almost amorphous mineral phases. The silica content remains stable at the applied temperature. The result: products with exceptionally high whiteness and impressive color neutrality – ideal for your application.
Product variants
Name | Functionalization | Basic material | Particle size | Powder color values | Color wetted |
|---|---|---|---|---|---|
| Silfit Z 91 | untreated | D50: 2.1 - D97: 9.0 | L*: 96.5 - a*: -0.2 - b*: 1.0 | Extra white |
Particle Size Distribution
All calcined products have a particle size that approaches that of the uncalcined basic material Sillitin Z 86.
Color Values
With regard to the CIELAB color values L*, a* and in particular b*, the calcined products are significantly brighter and more color neutral than the classic products Sillitin and Aktisil.
