Filler Grade Barite
barium sulfate pigments, barytes, are useful in a variety
of applications. They are chemically inert (e.g., acid resistant);
they have a high density, and a low oil absorption; and they
are radiopaque. Hence, they positively impact the performance
properties of formulated products. Barimite products are buff
colored because of their iron oxide content, and they represent
a low cost alternative to blanc fixe and white barytes in
applications where filler brightness is a secondary issue.
products have a neutral pH which is an advantage in alkali
Note: Barytes pigments perform well in high solids,
solvent and water borne applications. Like most mineral filler
pigments, coarser products tend to be more inexpensive than
- is designed for use in applications requiring an ultrafine
mean particle size and a very fine topsize. Applications include
high gloss enamels, thinner film coatings, primers (e.g.,
OEM & automotive), powder coatings, plastics, inks and other
products needing a topsize finer than 10um.
- is a general purpose grade of barytes. Its topsize is fine
enough for it to be used in many high gloss and semi-gloss
enamels, but it is also used in a variety of primers, inks,
plastics and other applications where a smooth surface is
required and/or where abrasion may be an issue. "XF" is often
the reinforcing filler of choice in black and darker colored
- is a 325 mesh filler that is commonly used in matte topcoats;
primers; brake pads; sound deadening; gasketing compounds;
sealants; rubber compounds; urethane & pvc foams; etc.
- is a 200 mesh filler that is used primarily in brake pads;
sound deadening; high build coatings; and sealants where its
larger topsize can be tolerated.
- is the coarsest barytes manufactured by CIMBAR Performance
Minerals. It is widely used in unique friction formulations
