ERPAL CAST
Alumina monolithic bottom solution
High-purity alumina concrete safety sublayer.
Typical application
ERPAL CAST is used in combination with ERPAL MORTAR as a safety layer under BPAL sintered alumina feeders to reduce risk of glass infiltration.
Must be vibrated with a beam during installation. For self-leveling application refer to ERGAL® SL CAST.
