NON-WETTING CASTABLES 不沾铝浇注料 Selangor, Kuala Lumpur (KL), Malaysia, Klang

Non-Wetting Castable 不沾铝浇注料
Specialized Refractory Solutions for Advanced Aluminum Processing 铝加工先进工艺专用耐材解决方案

Characteristics: Contains non-wetting agents that prevent molten metal from adhering to or penetrating the material.
Pros:
- Superior Anti-Penetration: Prevents molten aluminum or slag from infiltrating the lining, greatly extending service life.
- Easy Maintenance: Reduces slag buildup on furnace walls, making cleaning much easier without damaging the lining.
- Metal Purity Protection: Prevents impurities from the refractory from leaching into the molten metal.
Cons:
- Expensive: High cost due to specialized anti-penetration additives.
- Temperature Limitations: Non-wetting agents may lose effectiveness at extremely high temperatures (typically above 1200°C-1350°C).
- Storage Sensitivity: Additives may react with moisture in the air, resulting in a shorter shelf life.
