Presto Black Steel, a revolutionary room temperature blackening solution from Birchwood Technologies, is specifically designed for all iron and non-stainless steels. This liquid concentrate, when mixed with water, creates an immersion blackening solution that produces a durable, clean black finish on a wide range of steel surfaces. To ensure the longevity of the black coating, it is essential to seal it with a suitable rust preventative sealant, such as an oil or clearcoat.

What sets Presto Black Steel apart is its ease of use and versatility. To prepare the solution, simply mix the concentrate with tap water at a ratio of 10% by volume. Add fresh concentrate as needed to replenish the bath, ensuring consistent, high-quality results. The equipment required is minimal, with a tank made of polypropylene, PVC, or other acid-proof material, and racks, baskets, or barrels coated with polypro or PVC.

The blackening process itself is straightforward, requiring thorough cleaning, surface conditioning, blackening, and sealing. Begin by cleaning the parts to remove oils and shop soils using a gentle cleaner, followed by a rinse. Next, activate the surface with a surface conditioner, rinse again, and then immerse the parts in the Presto Black solution for 1-3 minutes, or until a uniform black finish is achieved. Finally, seal the finish with a rust preventative topcoat.

One of the greatest advantages of Presto Black Steel is its safety features. With no fumes produced during the process, ventilation is not necessary, making it an ideal solution for a variety of applications. Additionally, the solution can be filtered and recirculated using an acid-proof pump and 50-100 micron polypropylene filter element, reducing waste and minimizing environmental impact.
