Specialty Chemicals

The UCD® SF colorants have been designed for broad use in reactive industrial coatings. These products use a highly durable resin with closely controlled color strength and viscosity to permit reproducible color matches by volumetric machine dispensers or weight measurement in the plant.

BIANCOFISSO M0.7 PLUS is a high-quality, versatile white pigment designed to enhance the color and brightness of your products. This premium pigment is made from a unique blend of barium sulfate and zinc sulfide, ensuring superior performance and durability. Ideal for use in paints, plastics, and other applications, BIANCOFISSO M0.7 PLUS offers excellent dispersion, high opacity, and outstanding weather resistance.

325 Novakup® is a surface modified aka silane-treated ground silica. This performance filler has been preferred for over 35 years for its’ barrier prosperities in chemical and corrosion resistant applications. We would not hesitate to recommend 325 Novakup® for almost any application within polymer resins. Silane enhancements offer filler to resin cross-linking for improved mechanical and chemical properties within an application.

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.
