Refractory Mortar
Refractory Mortar is made into new type inorganic binder materials by choosing the same powder materials, adding inorganic binder, according to request of construction materials. There are four grades as below NT-1300,
NT-1400,NT-1500,NT-1600,each material is divided into light weight and heavy weight,we can choose relevant refractory mortar according to different request of construction materials.
Application of Refractory Mortar
*Building for industrial furnaces and kilns
*Binding for ceramic fiber blanket and board
