Luna-tex BBU is an optical brightener used to improve the brightness of products to make them more eye-pleasing. It is especially applicable for use in the surface coatings, glues and paper pulp.

Luna-tex BBU performs well under low temperatures, and its excellent chemical stability provides long-lasting performance.

Luna-cure DDS provides excellent high temperature properties and chemical resistance, with its fine particle size provides both enhanced reactivity and constancy in cure rates vs. coarser grades. Luna-cure DDS is easily dispersible in liquid resins and activation temperature is easily adjustable.

Luna-cure DDS can be used in applications for:

• One Component Adhesives

• Solid Epoxy Adhesives and Powder Coatings

• Prepregs and Film Adhesives

• Electronic Potting and Encapsulating Compounds

MINEX® ST OV100 (particle size 4) is a hydrophobic, surface-treated nepheline syenite (NS) designed for enhanced performance in coatings and adhesives. This grade is easily dispersed in a wide range of reactive solvent-borne and 100% solids resin systems. It is particularly effective in polyurea resin and coating systems where variable surface moisture can lead to film defects. MINEX ST OV100 is engineered to deliver superior performance in polyurethane, polyaspartic, polyester, and silicone resin systems. Ideal end-use applications include: Industrial maintenance, General industrial, Industrial floor, Powder coatings, Wood coatings, Specialty architectural, Aerospace, Automotive.

MINEX® ST is available in three particle sizes—4, 7, and 10—and two functional treatments: A100 and OV100. It offers similar optics, handling, gloss, and color acceptance as the equivalent MINEX grades, while delivering improved dispersion and higher loading capacity in select systems—enabling cost savings and reduced VOC content.

MINEX® ST micronized functional fillers and extenders are proven performance enhancers across a broad range of paints, coatings, adhesives, sealants, and inks. Select surface treatments were developed to further enhance chemical and stain resistance, washability, adhesion, weatherability, optical clarity, color retention in tinted systems, abrasion resistance, and tensile strength—by compatibilizing the mineral surface with the host binder systems and reactive chemistries.

MINEX and 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 0.1% crystalline silica, with no detectable free crystalline silica in the mineral complex. All MINEX ST grades are processed and sized in strict adherence to Covia’s QIPSM quality assurance programs, ensuring consistently uniform chemistries, tight particle size distributions, and controlled top sizes for reliable performance.
