Luzenac products are naturally occurring minerals that reduce the overall environmental impact of coatings formulations. The new, ultrafine Jetfine® range has been developed using proprietary micronizing technology that produces highly lamellar talcs with a high specific surface area. Jetfine 1A is a natural, inert, free-flowing talc powder with a top cut of 5µm and a median particle size of 1µm. Thanks to its fineness and high specific surface, it supports prime pigment dispersion and improves hiding power. The fineness of Jetfine 1A talc also enables its use in decorative emulsion paints without diminishing gloss.

Luzenac High Aspect Ratio (HAR®) talcs are the ideal solution for enhancing barrier properties in protective coatings. HAR talcs result from a proprietary delamination process that dramatically increases lamellar shape and aspect ratio, providing unparalleled barrier properties and significantly improved corrosion resistance. HAR is a natural, inert, free-flowing talc and is available in high-density, dust-free micro beads for easy dispersion.

Plastorit is an inert, functional mineral extender for high-performance coatings. By virtue of its mineralogical composition – a unique natural coalescence of mica, chlorite and quartz – Plastorit provides excellent wetting properties and low viscosity build up, which enables VOC reduction by up to 30%. Its pronounced lamellar shape supports the barrier effect, thereby improving anti-corrosion properties and durability in high-specification coatings.
