1800C (3270F) Hi-Purity Zirconia Coating - 634-ZO-LD

Hi-Purity Ceramic Zirconia Coating, 3270^oF (1800^oC), for coating and protecting heating elements of high temperature furnace.

Specification:

Highly-filled zirconium oxide-based coating. Produces a hard, chemically-resistant protective layer which is stable with aluminum, molybdenum, platinum, rhodium, and titanium. Idea for sealing porous ceramics and protecting other ceramics, graphite and metal structures up to 3270 ^oF (1800^oC). 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 Size: 17 oz./6oz. (Shipping in pre-mixed one part)

Recommended painting and curing procedures:

painting by brush (thickness less than 0.75mm)

Air setting at least 2 hours, then curing at 200^oF for 2 hours

Distilled water can be used to thin coating. Use 1-2% distilled water by weight
