Coatings for Stainless Steel - Presto Black® SSB Brush-On

Presto Black® SSB Brush-On Cold Blackening System

Presto Black® SSB Brush-OnAs a brush-on, Presto Black® SSB is used as is and reacts quickly to produce a non-dimensional black finish in approximately 1 – 3 minutes. The finish can be sealed with a protective oil and is suitable for use on precision tooling or machine components. Or, using an abrasive pad, working in the solution and highlighting, a distressed or antiqued type of finish can be produced for decorative or architectural metal works.

For manual, brush-on or sprayer application such as architectural finishing, antique sculpture work or scratch repair work, Presto Black® SSB is applied using a brush-on applicator technique or for larger surface areas a pump sprayer can be deployed. All workpieces must be thoroughly cleaned of oil and excess scale before blackening. Multiple applications of the chemistry may be required to achieve the desired grey/black finish. Reaction stop is also necessary and facilitated with a water rinse and forced air drying with compressed air, and then a final top coat sealant should be applied.
