Minex® ST 4 A100-10

1 of 23 products in this brand
Minex® ST 4 A100-10 is a functional filler that is produced from nepheline syenite, a naturally occurring, silica-deficient sodium-potassium alumina silicate. Automated scanning electron microscopy confirms that Minex® ST grades contain less than one-tenth of one percent crystalline silica. No free crystalline silica is detectable in the mineral complex. All Minex® ST grades are processed and sized with rigid adherence to Covia’s QIPSM quality assurance programs.

Functions: Extender, Filler

End Uses: Primer, Top Coat

Product Highlights

MINEX® ST functional fillers are produced from nepheline syenite; a naturally occurring, silica deficient, sodium- potassium alumina silicate. Automated scanning electron microscopy confirms they contain less than one-tenth of one percent crystalline silica. No free crystalline silica is detectable in the mineral complex. All MINEX® ST grades are processed
and sized with rigid adherence to Covia’s QIPSM quality assurance programs. Consistently uniform chemistries, size distributions, and top size controls ensure reliable performance.
