Malvern Minerals Novakup® L-207A Surface-Treated Lamellar Quartz Filler/Extender
Categories: Ceramic; Oxide; Silicon Oxide; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Novakup® is a surface modified or silane treated Novacite®. It has been used its barrier prosperities in chemical and corrosion resistant applications and as a filler/extender/reinforcing agent in polymers.

Novacite® quartz silica has closely controlled sizing that is used extensively in the coatings field. Novacite® has broad acceptance as silica in special purpose, product finishes OEM, automotive and industrial coatings. The unique, disc-like or lamellar shape of Novacite® makes it useful for coating systems where low oil absorption and improved barrier properties are desired. In coatings, the lamellar plate overlap parallel to the substrate surface. It has a polar, wettable surface and is very transparent in the UV and visible range. Its structure alpha (low) quartz, which is stable to 573°C. The crystallography of Novacite shows it is an uncommon variety of quartz, with anhedral or subhedral crystals that cleave along the principal axis of the molecular structure.
