SECAR® 712 is the new generation of 70% Al2O3 cement and possesses all the attributes of SECAR® 71 and more a unique scientific breakthrough: time stable properties!
As a result, SECAR® 712 achieves new levels of castable performance:
* tremendous stability of working time (both cement and castable) even after 12 months storage
* very small moisture pick-up in castable, especially beneficial in low cement systems
* outstanding compressive strength stability (6 hours) even after 12 months.
SECAR® 712’s shelf life is longer than 12 months and properties retained for 24 months in simulated ageing.
