Alternative to conventional aluminum anodize seals with an environmentally friendly seal process

摘要

Sealing of an anodized surface is a standard practice to complete anodizing process and finish. There have been various seal processes that use hot deionized water (boiling temperatures), use of metal salts (Nickel Acetate, etc.), chromate sealing (such as Sodium Dichromate) and some other proprietary chemistry. This paper will describe a new process for sealing anodized aluminum with environmentally friendly, room temperature application and substantially less process time with outstanding results.
