Coverguard
Stops graphite burning to above 1800 F, reduces
carbon loss and costly component replacement, high emissivity.

MW-50 Paste
A fiber-strengthened silicon carbide paste that can be painted
(or troweled to form a thick, stucco shell if desired) to provide a hard, wear and abrasion resistant layer that is non-reactive to most molten metals. MW-50 is ideal for soft ceramic bodies such as pulp-molded parts that often degrade in service due to their soft nature. MW-50 can be built-up to most any thickness and is ideal for repairing graphite parts that have been eroded or damaged thereby saving the expense of replacement. MW-50 also stops graphite oxidation to 1000 C (1800 F) and can extend the use of graphite to these higher temperatures.

Combo Coatings
Combo Coatings are sometimes used on graphite to give reduced oxidation and also good nonwetting due to a Boron Nitride topcoating onto Coverguard.
SC
This water-based coating results in hard, abrasion-resistant coatings that have high-emissivity and are usable on all graphites/carbons like ordinary house paint.
The TYPE SC coating inhibits graphite oxidation to its maximum
recommended use-temperature of 1000 C.

SC1400
This water-based coating results in hard, abrasion-resistant coatings that have high-emissivity and are usable on all graphites/carbons like ordinary house paint.
The TYPE SC 1400 provides protection extended to 1400 C and even
to 1600 C for short-time use.

Y
This water-based paint is a water-based suspension of 99.99% pure Yttrium Oxide, the most thermodynamically stable oxide available. Whenever metal purity is a prime consideration during melting and casting operations, yttria
can be considered the most chemically resistant material
available. Type Y usage is limited to 1500 C with
carbon in a vacuum and is not recommend for usage in air.
More Info Call for current price ... this paint is not available online due to the present unstable/fluctuating prices for Rare Earth Oxides.
YK Paint
This is a low viscosity, non-aqueous-based, yttrium oxide coating. Type YK readily penetrates porous and fibrous ceramic bodies. Compared to Type Y, the Type YK coating is somewhat softer and higher purity after outgassing [with Type YK containing only 0.3% glassy-carbon phase after heating] and also outgasses at a lower temperature of only 350 C – ideal for coating molds where minimum outgassing
temperatures and amounts of volatiles are desired. Type YK
is not recommended for usage in air.

Zircwash
Paintable Zirconium Oxide coating; silica free, gives high purity
non-ferrous castings, utility to 1900 C.
