SILBOND® CONDENSED is a ready form of silicic acid, appears in a clear and low viscosity liquid. SILBOND® CONDENSED is tetraethyl orthosilicate and used as a raw material for acid-or alkali-catalyzed hydrolysis and subsequent condensation reactions, commonly known as the sol-gel process. SILBOND® CONDENSED offers the ability to improve chemical and thermal stability during its application. SILBOND® CONDENSED is most commonly used in glass, metals, pigments, fillers, and synthetic fibers coating, silicone rubber systems and sealing composition applications.

MINEX® ST OV100 (particle size 7) 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.

Litex N VT-LA is an aqueous, colloidal dispersion of a carboxylated butadiene-acrylonitrile copolymer with a medium acrylonitrile level. The dispersion contains an anionic emulsifier system and is stabilized with an antioxidant. Litex N VT-LA is used mainly to manufacture dipped goods and should be vulcanized. These articles have a good resistance to oils, petrol, greases and plasticizers.

REVACRYL A 8202MB is a fine particle size, surfactant stabilised aqueous dispersion of a styrene and methacrylic ester-acrylic ester copolymer. Offers good water resistance with very high pigment binding characteristics. REVACRYL A 8202MB is a fully ecological coalescent free binder suitable for production of high PVC coating materials (interior wall and facade paints) with low content of VOC. Key Advantages: high pigment binding capacity, very good compatibility with pigments and extenders, high film elasticity, low odour.
