"Type BN"
High-Purity Boron Nitride Paint
|
|
Description :
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.
BN High Purity
고순도
질화 붕소 페인트 즉 BN Hi-Purity Boron
Nitride Paint는 경제적이고, 비-인화성이며, 물-기반의
고순도 BN이며, 일반 가정에서 사용하는 페인트와 마찬가지로 스프레이하거나
적시거나 붓으로 칠하는 등 쉽게 사용할 수 있으며, 아주 얇게 코팅하거나
매우 두껍게 코팅할 수 있는 고온페인트입니다. 다공성/비다공성 가릴
것 없이 거의 모든 금속 세라믹 그라파이트에 본딩이 잘되는 코팅제
입니다
TYPE BN Hi-Purity Paint 는
비부착성 이형 촉매제로 넓게 사용되고 또 도가니/주형틀 등을 포함하여
고순도 보론코팅이 필요한 거의 모든 사양에 적용할 수 있으며,
태우면 98% 이상의 BN을 내어 놓습니다
TYPE BN Hi-Purity Paint 는
진공분위기 또는 불활성분위기에 추천합니다. 600 C이상으로
가열되면 바인더의 위상이 분해되어 유리질 카본으로 변하며 이 것이
고온 점착성을 제공하게 됩니다. 그러나, 산화분위기에서 600 C이상으로
가열하면 코팅의 성격이 부드럽게 변하며 점착성과 내 마멸성이 낮아
지게 됩니다

Use Instruction
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. |
