"Type BN" High-Purity Boron Nitride Paint

Description

ZYP TYPE BN Hi-Purity Boron Nitride Paint is an economical, non-flammable, water-based, high-purity formulation specifically designed to:
• Be used like ordinary house paint, which can be applied by air-spraying, dipping or brushing to yield very thin to very thick coatings and
• Bond to most any porous or nonporous material, such as graphite, ceramics, and metals.

TYPE BN Hi-Purity Paint has found wide use as an anti-stick release agent and as a crucible/mold coating as well as most any use where a high-purity coating is demanded. Yields greater than 98% BN upon firing.

TYPE BN Hi-Purity Paint is recommended for vacuum or inert atmospheres. Upon heating to above 600 C, the binder phase decomposes to form glassy carbon, which provides the high-temperature adherence. If heated to above 600 C in an oxidizing atmosphere, the coating can become softer, exhibiting reduced adherence and abrasion resistance.

1. Resuspend by shaking or rolling.
2. Clean surfaces of grease, dirt and loose materials.
3. Apply by brush or spray.
4. Air dry.
5. Place into use.

NOTE: Recommended for vacuum and inert atmospheres. Becomes softer, with reduced adherence, if used in oxidizing atmospheres above 600 C.

These recommendations are believed to be accurate. No guarantee of their accuracy is made and the products are sold without warranty, expressed or implied. Purchasers shall make their own tests to determine suitability of their use.
