PBN Coatings

Characteristic

Ultra-high purity (>99.999%) and excellent hermeticity

Excellent electrical insulation

Extremely low outgassing rate at elevated temperatures

Excellent chemical inertness: no reaction with acids, alkalis, salts, or organic solvents at high temperatures

The coating adheres tightly to the substrate and is not easily peeled off
