Refractory Mortar
The refractory mortar is a new-type inorganic binding material, made from top-quality refractory powder, high-strength and high-temperature resistant chemical binding agent and additive in accordance with the requirements for masonry refractory brick materials. The refractory mortar is perfect for kiln masonry in need of small gap, great air tightness, high setting strength, etc.
Features of Refractory Mortar
1. Extremely high setting strength, great integral structure of masonry
2. Great air tightness, extraordinary corrosion resistance, long service life
3. High chemical stability and small shrinkage under high temperature
4. Excellent slag resistance, very small gap in masonry, convenient for construction
