Coal Dust Ultra

"The "Dynamic Resilient Shield" (Superior Surface Finish) Unlike standard seacoal that relies purely on high volatiles—which can cause pinholes and rapid sand degradation—Coal Dust Ultra utilizes our exclusive modification technology. It generates a robust, high-temperature protective barrier that remains stable even under the extreme pressures of automated molding lines, effectively preventing metal penetration and sand fusion for a silk-smooth casting surface.

Sustained Reducing Atmosphere (Long-Lasting Protection) Optimized for the fast-paced pouring cycles of automated foundries, our proprietary blend triggers a controlled gas evolution upon contact with molten metal. Instead of a rapid "flash burn," it maintains a sustained reducing atmosphere throughout the critical cooling phase. This continuous protective barrier acts before sand-metal reactions can occur, ensuring a clean, effortless shakeout every time.

Clean Sand Technology (Ultra-High LOI > 93%, Minimal Ash) With an exceptionally high Loss on Ignition (LOI > 93%) and precision-balanced Volatile Matter, Coal Dust Ultra keeps your sand system breathable and pure. By drastically reducing the buildup of useless ash and dead clay, it minimizes gas-related defects and significantly extends the lifecycle of your sand circuit, even in the most demanding high-speed production environments.
