ERPLAST® 20 CEMENT
Alumina-zirconia-silica (AZS) sealing cement
Alumina-zirconia-silica (AZS) cement to seal and joint alumina-zirconia-silica (AZS) surfaces.
Typical application
Easy-to-use cement with good malleability at low temperatures. Ideal solution for jointing during construction and repair operations : jointing of alumina-zirconia-silica (AZS) skewback and alumina-zirconia-silica (AZS) blocks, jointing of alumina-zirconia-silica (AZS) crowns and gable walls, etc.
ERPLAST® 20 CEMENT's good corrosion resistance. Grain size suitable for thick layer (>10mm) and to fill wide joints.
Due to its high alumina content it cannot be used in contact with silica. For application with contact with silic check out the ERPLAST® Z PATCH.
