Features and Benefits

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.

Applications & Uses

Coating Type
Applications

Baryte will provide UV resistance and weatherability: due to its inertness, baryte supports good UV and weatherability performance to sealants and adhesives when used outdoors.
