A new boron nitride ceramic spray coating is helping glass manufacturers improve mold performance. The coating delivers reliable lubricity during high-temperature glass forming processes. This reduces friction between molten glass and mold surfaces. As a result, glass products come out smoother and with fewer defects.

The coating sticks well to metal molds used in pressing or molding glass. It stays stable even when temperatures rise above 1000°C. Unlike traditional release agents, it does not burn off or leave residue. This means fewer interruptions for cleaning or reapplication. Production lines can run longer without stopping.
Glass makers have tested the spray in real-world settings. They report less sticking and easier part removal. Mold life also increases because the coating protects against thermal shock and chemical wear. Maintenance costs go down while output quality goes up.
Applying the coating is simple. Workers spray it directly onto clean mold surfaces. It dries fast and forms a uniform layer. No special equipment is needed. The process fits easily into existing production routines.
Boron nitride has long been known for its heat resistance and non-wetting properties. Now, in spray form, it offers a practical solution for everyday glass manufacturing challenges. Companies using it see immediate benefits in both efficiency and product finish.
The coating works across many types of glass, including container glass, tableware, and technical glass parts. It suits both small batch runs and high-volume operations. Users say it performs consistently over time without degrading.

This innovation comes at a time when glass producers face pressure to cut waste and boost throughput. The boron nitride spray helps meet those goals without major changes to current systems.
