New Presto Black® SSB room temperature Stainless Steel blackening process is an immersion or brush-on solution for most stainless steel alloys and substrates. Creating an esthetic appealing finish, Presto Black® SSB can easily be used in production finishing, for manual touch-up needs, or for distressed decorative or architectural metalworking.
Presto Black® SSB reacts quickly and produces a non-dimensional black finish in 1-3 minutes in most brush-on applications. When used in-house for volume immersion finishing, the process is best implemented with a series of tanks for cleaning, rinsing, blackening, final rinsing and applying a final topcoat sealant for long term protection. The immersion process takes only 12-15 minutes to complete a full batch of parts. Pre-engineered finishing lines in sizes suitable for most finishing requirements are available from Birchwood Technologies.
