Portaryte® 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®fillers are successfully used in an extended range of paint & coating applications such as industrial, marine and powder coatings.
Portaryte®B 50/10 have been specially developed for powder coating applications. The specially engineered particle size distribution makes it effective matting fillers for low thickness powder coatings, where standard barite fillers give higher gloss and need to be additionally combined with matting waxes to achieve the required matting.
