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 T 66W50 is an aqueous dispersion of a carboxylated styrene-butadiene copolymer. The dispersion was specially designed for the impregnation of needlefelt and also for the finishing of woven carpets. Litex T 66W50 give the finished article a medium hard handle. Contains an antioxidant. Litex T 66W50 is characterised by a high mechanical stability, and as a result does not form deposits, even after long periods of operation on the squeeze rollers. The fine particle size of the dispersion coupled with its high mechanical stability makes it suitable for spraying (e.g. binding of non woven fabrics). The blockage of the spray nozzle over long periods of production is not a problem.

SR-PPE-2000 is a brownish yellow transparent viscous liquid polyphenylene ether resin with low molecular weight, end-capped with vinylbenzyl ether groups. It features low dielectric properties, high heat resistance, low water absorption, and low viscosity, making it ideal for electronic applications such as ultra-low dielectric loss CCL substrates and PWB insulating films.
