| Hardeners are inorganic liquid hardening agents which, when applied to blanket, modules or board, produces a hard surface finish with increased resistance to mechanical abrasion and to gas flow erosion. Applications: Where enhanced resistance to erosion by high velocity gases is required, such as occur around burner block assemblies, blanket modules or board can be hardened after installation. A final hardening spray is often given to the blanket hotface linings of furnaces, ductwork, etc. where gas flow is significant, or when it is desired to impart some resistance to mechanical damage. Surface hardening is also recommended for applications involving contact with molten non-ferrous metal, e.g. launder linings. Information provided by Morgan Advanced Materials |
