CAS: 12042-68-1
The ACA is an inorganic compound mainly used as a binder in the manufacture of ceramic products and the construction industry. This material outstands other binders by its amorphous structure, which provides it with unique properties such as superior strength and durability for specific applications. It has been developed in order to provide improved adhesion and to force the integrity of materials that require very high thermal and chemical stability. Over these years, the ACA has proved to be indispensable in various industrial applications, especially in construction and application for hydrolytic materials.
Unlike traditional binders, the ACA provides improved temperature resistance in service and is therefore very suitable for any application involving exposure to extreme conditions, e.g., when making high-strength cement and concrete.
