SECAR Plenium® is a hydraulic binder with an alumina content of approximately 80%. It is suitable for use in a wide range of refractory applications and it simplifies the castable development process by reducing the number of additives required in a formulation. In addition, SECAR Plenium® reduces production complexities with fewer components and improves placing performance. SECAR Plenium® is an engineered and innovative cement which provides advanced built-in formulation technology. It is optimised for use in conjunction with a wide variety of aggregate types. It is particularly recommended for high purity castable systems, such as alumina rich systems, with and without fume silica and castables containing magnesia and spinel. SECAR Plenium® is especially
