Reliable Sealing Refractory Mortar Mullite Material High Temperature Resistance
The Description:
The refractory mortar is composed of fine powder and special bonding agent, which produces good strength and forms high strength bonding joints under the condition of natural drying in the air, and finally forms the brick masonry similar to the whole prefabricated structure.
Product characteristics
Excellent performance
Ideal plasticity and water retention, drying and baking shrinkage is small, high refractoriness, high combination strength
Good resistance to chemical erosion, chemical properties are stable
Typical application
1.Used for laying heat-insulating bricks, special heavy bricks and high aluminum heavy bricks
2.It is used to prevent the air and hot air flow from invading the masonry
3.It is used to prevent the erosion of slag and molten metal on the brick joints
