Tru Temp® Black Oxide Finish Is Ideal For Machine Tool Components – It’s Durable, Attractive And Resists Corrosion With Many Application Benefits

TRU TEMP® Black Oxide

High value tooling such as toolholders, workholding and turret press tooling takes on an attractive, protective black oxide finish when finished with the Tru Temp low temperature, non-polluting black oxide system from Birchwood Technologies.

Extremely durable, the Tru Temp process provides a satin black magnetite coating, 20 millionths thick (0.54 micron) with no effect on component material hardness or tensile strength. Components such as gears, sprockets and couplings operate with no functional change while the finish adds substantial protection. Tests verify Tru Temp withstands up to 100 hours of neutral salt spray (ASTM B 117) or several hundred hours of humidity (ASTM D 1748).

Birchwood Technologies introduces Presto Black® SSB Room Temperature Blackening Process For Stainless Steel

Room Temperature Blackening Process For Stainless Steel

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.
