Hengrui fireproof al2o3 binder is compounded specially for the stickup between ceramic fiber products, and it also can be used to construct furnace walls. It is ropy liquid with color of slightly yellow, which can be drying in the air with very good felting strength and come up with construction similar to firebricks. For bonding under 300-1800 °C high temperature conditions, especially suitable for high temperature furnaces masonry or repair.

Hengrui fireproof al2o3 binder is a colloidal silica compound for treating surfaces of ceramic fiber products to provide a degree of surface hardness and resistance to erosion. It can extend the usage life of the refractory materials. Rigidizer can use surface spraying or besmear to finish construction, freezing should be avoided.

²  High felting strength, Overall masonry structure.

²  Air tightness,resistance to chemical attack and long service life.

²  High softening temperature, low shrinkage at high temperature.

²  Good slag resistance, low porosity, excellent chemical stability.
