Butvar® B-79 is a thermoplastic, polyvinyl butyral resin which offers a unique combination of properties for coating or adhesive applications. The use or addition of polyvinyl butyral to a system imparts adhesion, toughness, and flexibility. PVB retains the clarity of the coating and offers reactive hydroxyl sites for crosslinking with thermoset systems. The broad solubility range of Butvar® B-79 allows it to be formulated into many applications.

DAOTAN TW 6450/30WA is recommended as the NMP / NEP- free alternative for DAOTAN (V)TW 1236. Like the latter, DAOTAN TW 6450 is a polycarbonate-based, high molecular weight Polyurethane dispersion. Dried at ambient temperature, DAOTAN TW 6450 provides clear, crack-free films without further addition of organic solvents or additives. These films exhibit excellent elasticity and mechanical properties and very good adhesion to different plastic substrates like e.g. ABS, PC, PA, PVC, PC/PBT. Accordingly DAOTAN TW 6450/30WA is particularly recommended for waterborne plastic primer and waterborne auto OEM Basecoats with outstanding requirements regarding stone chip resistance properties. A further use is as modifier resin to improve stone chip resistance properties of e.g. auto OEM primer surfacer formulations. DAOTAN TW 6450/30WA can be used as an adhesive for pharmaceutical and food packaging applications. It provides excellent peel strength and long-term humidity resistance. It is ready to use; no further formulation is needed.

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.
