General Characteristics of Refractory cement Secar 71
SECAR® 71 is a versatile hydraulic binder with an alumina content of approximately 70%, which is designed to be used at temperatures in excess of1400°C.
SECAR® 71, a pure cement manufactured by the sintering process, contains only calcium aluminates. The high calcium aluminate content provides characteristics ideally suited for refractory applications where rapid hardening combined with excellent mechanical resistance and high temperature performance are required.
As a binder, SECAR® 71 reacts with most organic and mineral additives to achieve exceptional flow with highearly compressive strength. SECAR® 71 is produced and controlled with in a quality management system that is certified according to ISO9001.
SECAR® 71 does not contain any additives.
