- Applications
- Chemical resistance: due to its inert nature, ATH will provide good chemical resistance compared to conventional fillers.
- Gloss control: with the availability of ultrafine ground ATH (Portafill A7) and a product with an optimized particle size distribution (Portafill A25/10), it is possible to apply coatings with a broad range of gloss levels.
- Increasing extruder output: the optimized particle size distribution of Portafill A25/10 provides better free-flowing properties. As a result, the material is easier to dose into the extruder, so the residence time inside the extruder can be optimized.
- UV resistance: being insensitive to UV radiation, ATH will reduce the coating’s degradation.
- Water spotting resistance: powder coatings formulated with ATH show less tendency for water spotting then similar coatings formulated with barium sulfate.
