 Hi-Purity Ceramic Zirconia Coating, 3270oF (1800oC)

for coating and protect heating elements of high temperture furnace

Highly-filled zirconium oxide-based coating. Produces a hard, chemically-resistant protective layer which is stable with aluminum, molybdenum, platinum, rhodium, and titanium. Ideal for sealing porous ceramics and protecting other ceramics, graphite and metal structures up to 3270 oF (1800oC). Exceptional for coating resistance wire heating elements, SiC and MoSi2 heating elements in high temperature furnaces, protecting them from residue buildup which causes arching and reduced element life.


Total: 17oz. / 6oz. ( shipping in pre-mixed one part )
