                                        PBN Coating

           1.  Product Instruction

                In High temperature, high vacuum, and High purity environment,
                PBN is usually used as coating material to protect the graphite. 
                PBN coating can avoid the graphite heating unit to volatilize in                 high temperature
          2.   Product Feature
                
    High purity (99.999%)
                High insulativity
                Low outgassing in high temperature
                Coating can combined with substrate tightly, not easy to peel off
                High resistivity to chemical corrosion in high temperature
                High density and effectively prevent volatilization of substrate
