FUNCTIONAL FILLERS AND EXTENDERS

FEATURES AND BENEFITS

MINEX® micronized functional fillers and extenders are proven performance enhancers in a broad range of paints, coatings, adhesives, sealants, and inks. Excellent brightness, tint retention, and weatherability can be achieved in exterior paints. Improved color, sheen uniformity, chemical and stain resistance, and durability result when MINEX is used in interior paint formulations. MINEX is easily dispersed in all conventional vehicle systems, and low oil absorption permits high loadings in adhesives, sealants, and aqueous and alkyd based paints. Multiple grades are available to provide optimal performance in a variety of applications. While the preferred MINEX product is application dependent, coarser grades offer cost effective gloss and sheen control and can add texture. The intermediate grade MINEX 4 offers application versatility for a wide range of architectural and industrial uses. Finer MINEX grades are preferred for higher gloss coatings and are also the preferred choice for powder and clear paint systems.

MINEX® fillers are produced from nepheline syenite; a naturally occurring, silica deficient, sodium-potassium alumina silicate. Automated scanning electron microscopy confirms that MINEX contains less than one-tenth of one percent crystalline silica. No free crystalline silica is detectable in the mineral complex. All MINEX grades SM are processed and sized with rigid adherence to UNIMIN's QIP quality assurance programs. Consistently uniform chemistries, size distributions, and top size controls ensure improved structural and chemical performance with minimal resin demand.
