Portaryte® C micronized functional fillers are used in a broad range of applications. The most important characteristics are:
- Excellent chemical inertness (outdoor and chemical applications)
- Low level of impurities, such as transition and heavy metals
- Low content of quartz (low abrasiveness, no health issues)
Because of these characteristics, Portaryte® C fillers are successfully used in an extended range of paint & coating applications such as industrial, marine and powder coatings.
