ZYP Coatings Boron Nitride Aerosol Lubricoat 2 Pack - Glass Mold

In this review the ZYP Coatings Boron Nitride Aerosol Lubricoat 2 Pack is evaluated for artists and metalworkers who need a dependable, high-temperature release agent. The bottom line: this aerosol excels at preventing glass from sticking during slumping and fusing and also performs well on aluminum and other metals, so buyers wanting to reduce broken molds and stuck castings will appreciate its reliability. The review focuses on real use cases, temperature limits, and why this product is a practical workshop staple rather than a decorative spray.

Key Features

• High temperature tolerance: Usable in air to 1000C and higher in inert or vacuum conditions, which protects molds and castings across common kiln and furnace processes.
• Glass mold release: Designed specifically for glass slumping and fusing, it reduces the risk of broken molds and stuck pieces during heating and cooling cycles.
• Metal anti-stick: Formulated to act as an anti-stick for molten aluminum, magnesium, and zinc, making it useful for many foundry tasks.
• Multi-application lubricant: Also useful for extrusion and other metal applications where a high-temperature non-stick surface is needed.
• Weld and braze protection: Functions effectively as a weld spatter or braze stop-off, helping protect surrounding surfaces during welding or brazing operations.

Who It's For

This product is aimed at glass artists who slump and fuse frequently and need a dependable release agent to avoid ruined work and damaged molds. It is also a strong choice for small foundries, metal fabricators, and hobbyists working with molten aluminum, magnesium, or zinc who want a straightforward aerosol option.

Those who should look elsewhere include users needing a water-based or low-odor indoor spray for general purpose lubrication, or projects that require a specialized coating with visible color or finish properties; this is a performance coating made for high-temperature release and protection rather than cosmetic effects.

Pros & Cons

Pros

• Proven effectiveness on glass molds, reducing sticking and broken pieces during slumping and fusing.
• High temperature ratings make it suitable for kiln and furnace use in air, inert, or vacuum conditions.
• Versatile for metalwork: anti-stick for molten metals and useful as a weld spatter or braze stop-off.

Cons

• As an aerosol coating, it is a workshop chemical and requires proper ventilation and handling rather than casual indoor use.
