PORTARYTE B4

PORTARYTE B4 is a micronized natural baryte with a mean particle size of 1.5 μm. It has excellent chemical inertness making it suitable for applications requiring durability against outdoor and chemical exposures. PORTARYTE B4 contains low levels of impurities such as transition and heavy metals, providing formulation stability. Its low quartz content reduces abrasiveness, avoiding potential health issues. These characteristics allow PORTARYTE B4 to deliver long-lasting, smooth finishes. PORTARYTE B4 fillers have been specially developed for applications requiring high opacity and gloss retention.
