Hubbard-Hall’s Black Magic Infusion Powder gives a performance and quality black finish to a wide range of steel, being specifically formulated to minimise the common problem of red iron oxide adherence. The infusion – a solution of oxidising salts – is a free-flowing, dust-free granular mixture, used at a low temperature (138-141C), for blackening a wide range of carbon, alloy, and hardened tool, steels. However, for easily blackened stainless steel or cast iron applications, Hubbard-Hall’s Black Magic SS formulation is recommended. With its unique blend of activators, rectifiers, catalysts and surface-active agents, Black Magic Infusion Powder, produces the darkest black available, as well as providing the user with reduced immersion time without sacrificing quality. To obtain the best possible results, a properly maintained and controlled approach should be adopted when using Black Magic Infusion. Automating the water supply and maintaining temperature with an automatic controller is highly recommended, to ensure a consistent, uniform and high-quality black finish. Details of automated temperature controllers and water inlet valves for immersion tanks are available upon request. Finally, unlike other conventional formulations, the unique make-up of the infusion eliminates the necessity for frequent sludge cleaning.
