Minex® 12 belongs to the Minex® range of functional fillers and extenders, which are proven performance enhancers in a broad range of paints, coatings, adhesives, sealants, and inks. With its use, excellent brightness, tint retention, and weatherability can be achieved in exterior paints. In interior paint formulations, it improves color, sheen uniformity, chemical and stain resistance, and durability. This product is easily dispersed in all conventional vehicle systems. Its low oil absorption permits high loadings in adhesives, sealants, and aqueous- and alkyd-based paints.

Functions: Extender, Filler

End Uses: Clearcoat, Powder Coating, Radiation Curable Coating, Waterborne Coating

Compatible Polymers & Resins: Alkyds
