Cold Patching Gunning Mix Al2O3 65%
Al2O3 65% cold patching gunning mix for planned furnace lining maintenance during scheduled shutdowns. High cold crushing strength and low shrinkage restore worn linings in rotary kilns, EAF, and steel ladles.
Monolithic RefractoriesMax Temp: 1600°C
// Key Features
- High cold crushing strength providing load-bearing capacity in thick repair patches
- Excellent adhesion to both fired and unfired refractory substrates
- Low drying and firing shrinkage preventing crack formation after repair
- Extended open time allowing thorough large-area cold patching during shutdown
