Barium Sulfate Extenders
Sparmite ® Barytes, from Elementis Pigments, is a line of extender
pigments. The Sparmite products are specified because of their chemical
inertness and insolubility, high purity, high refractive index, low
abrasiveness, low oil absorption, ready wettability, easy grinding
and high density. Applications for Sparmite Barytes include industrial
primers, trade sales paints, gloss enamels, powder coatings. Their
low absorption imparts excellent flow and leveling properties. These
chemically inert materials provide clean tints and colors. When used
in semi-gloss latex paints, they speed the dry time, give harder
and tougher film properties and have little effect on gloss.
