ALFISO™ High Temperature Coatings

ALFISO refractory coatings are designed to provide a protective surface layer over ceramic fiber products, to resist chemical attack, mechanical wear, high gas velocity or non-wetting treatment against aluminium, brass or bronze alloys. Coating 1500A: Protective coating for ceramic fiber products against mechanical wear or high gas velocity in furnaces.

► Coating 1500E: Same application as 1500A, with lower viscosity, provides thin coating.
► Coating 1500N: Same application as 1500A, but without organic composites.
► Coating BS: Coating for launder or other ALFISO vacuum formed products for aluminium applications.
► Coating BS4: Coating for launder or other ALFISO vacuum formed products for aluminium applications, suitable for special alloys if the content of Mg or Na is high
