BN Boron Nitride Glass Release Brushable is an easily applied Boron Nitride coating that is designed for ceramic molds used for glass slumping.  This water-based “bulk” paint is non-hazardous which allows for much lower shipping and handling costs as compared to the solvent-based aerosol or bulk solvent-based paint.氮化硼玻璃脫模可刷涂是一種易于應用的氮化硼涂層，專為用于玻璃坍落度的陶瓷模具而設計。 這種水性“散裝”涂料是無害的，與溶劑型氣溶膠或散裝溶劑型涂料相比，運輸和處理成本要低得多。
