Cold sealing, also known as room temperature sealing uses nickel fluoride for the sealing reaction. Operating temperatures range from 80 to 90F, with temperature regulation being recommended. Cold sealing has a sealing mechanism that is unique from other seal methods. Good management practices can realize cost and environmental benefits. Cold sealing also affords excellent alkaline resistance. In conjunction with proper anodizing techniques, cold sealing can enhance the lightfastness of dyed anodized articles. Cold sealing meets MIL-A8625 requirements, though other specifications may offer limitations.
