HALOX® SZP-395 is a white, nonrefractive, corrosion inhibiting pigment used in protective coating systems. HALOX® SZP-395 is our most efficient and versatile corrosion inhibitive pigment. It is recommended for use in a wide variety of resin systems and is equally effective in such resins as: alkyds (both traditional and high solids), epoxies, latexes, water reducible alkyds, high acid value resins, catalyzed baking systems, and vinylidene chloride latexes. The fine particle size and low oil absorption of HALOX® SZP-395 makes it the pigment of choice in thin film applications. Application: Recommended loading levels range from 2-5% based on total formula weight in many waterborne systems. and recommended loading levels range from 3-7% based on total formula weight in traditional solventborne coatings.

HALOX® Z-PLEX® 250 is a white, non-refractive, corrosion inhibiting pigment used in various protective coatings. It is classified as Zn3(PO4)2.2H2O (dihydrate). HALOX® Z-PLEX® 250 is compliant with ASTM D6280, Specification for Zinc Phosphate Pigment Type I. Recommended loading levels range from 5-10% based on total formula weight.

HALOX® ZINC PHOSPHATE is a white, nonrefractive, corrosion inhibiting pigment used in protective coating systems. It is generically identified as zinc phosphate-dihydrate. HALOX® ZINC PHOSPHATE exhibits a narrow particle size distribution: upper particle size limit of 10 microns, mean particle size 5 microns. This pigment has a high degree of versatility. It is a standard corrosion inhibitor for most high-performance resin systems such as types of vinyl, chlorinated rubbers, and epoxies. It is recommended for high acid value resins, catalyzed baking systems, and vinylidene chloride latexes. HALOX® ZINC PHOSPHATE is also recommended for thin film applications (1 mil or 25 microns). HALOX® ZINC PHOSPHATE is compliant to ASTM D 6280-98 Specification for Zinc Phosphate Pigment Type I. Recommended loading levels range from 5-15% based on total formula weight.

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.
