TYPE 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. This coating is commonly used for
• Reactive Metal Melting/Casting
• Lubricant for Superplastic Forming
• Anti-stick Release Coating for Diffusion Bonding, Hot-press De-canning & Sintering
Yttria properties that drive its selection include refractoriness; stability with carbon; low electrical and thermal conductivity; moderate thermal expansion; highest stability with the most reactive metals and alloys; high-temperature lubricity. The paint yields a relatively soft and pliable coating that is easy to apply. On heating to above 750 C, the liquid coating evolves water and carbon oxides slowly, becoming fully outgassed – leaving only 0.7% glassy-carbon phase, with the balance being yttria. This white-colored coating has a specific gravity of 1.8 and a neutral pH in its liquid form – utilizing a cellulose binder along with 45% of yttrium oxide active ingredient. Type Y is medium to-low viscosity and can have a 400 sq.ft. per gallon coverage – usable on all substrates. Maximum recommended use-temperature is 2000 C in inert or vacuum atmospheres. Type Y usage is limited to 1500 C with carbon in a vacuum and is not recommend for usage in air. For use in all environments, including air, Y-Aerosol or
Y-AER-BRUSHABLE are offered [Refer to Aerosol Refractory Spray Datasheet] .
