Luzenac products are naturally occurring minerals that
reduce the overall environmental impact of coatings formulations. The new,
ultrafine Jetfine® range has been developed using
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.
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.
