WAM® AL II G; Gun Mix

WAM® AL II G is a gun mix version of the WAM® AL II castable. It maintains all the advantages of the castable system, including the microporosity, in a gun mix version. This means the material is non-wetted and unreactive with molten aluminum.

 

Typical application areas are larger installations where time is of the essence. WAM® AL II G exhibits outstanding gunning characteristics, inherently low rebound, and can be used to repair original WAM® AL II  cast installations after several years of use.

Because of the non wetting and non reactive nature of the castable, there is little cleaning of the old surface required. However, it is recommended that the old surface be roughed up so as to create ’holds’ for the new gunned material.

 

WAM® AL II G  has been installed in several furnace walls from the upper to lower sidewall areas. It can also be shot overhead to repair any cracks in the roof which may form over time.
