Outstanding Features of KERUI High Alumina Mortar

High Bonding Strength

The high bonding strength of KERUI high alumina mortar ensures effective adhesion to various surfaces. This property provides a robust bond between materials. This is crucial in applications where a strong and durable connection is required, such as in the construction of refractory linings.

Good Sealing Performance

The refractory mortar mix product has good sealing performance. It is beneficial in applications where preventing the penetration of gases, liquids or other substances is essential. This feature helps maintain the integrity of structures, particularly in environments where protection against external elements is crucial.

High Corrosion Resistance

KERUI high alumina mortar exhibits high resistance to corrosion, which makes it well-suited for use in environments with aggressive chemical or acidic conditions. This corrosion resistance ensures the longevity and stability of the materials it bonds, especially in industries where exposure to corrosive substances is common. Therefore, this product is suitable for various high temperature kilns.

Low Shrinkage

Low shrinkage is a valuable characteristic of mortar materials. It means that the mortar undergoes minimal volume reduction during curing or exposure to high temperatures. Low shrinkage helps prevent cracks and maintains the structural integrity of the application, particularly in high-temperature environments where expansion and contraction can be significant.
