According to Birchwood Technologies (Eden Prairie, MN), manufacturers needing immediate corrosion protection on small quantities of parts now can get it with all of the quality of larger finishing systems using the Mini PRESTO BLACK line. The BK-1 line is an ideal low cost alternative and/or substitute for large scale finishing. This mini PRESTO BLACK room temperature blackening system for iron and steel is great for small production operations, says the company, which require robust corrosion resistance and galling protection on critical surfaces for machine components. The PRESTO BLACK process produces a virtually non-dimensional coating of less than 0.5 micron thickness and is ideally suited for components that require a black finish for visual appeal and rust protection. Benefits include:
- A short fifteen-minute process that eliminates the hazards of the hot oxide process by operating at room temperature of 70°.
- High corrosion resistance; tested for up to 800 hours humidity exposure when sealed with an appropriate rust preventive.
- The ability to be used effectively on hot rolled steels, alloy steels, tool steels, as well as cast iron, forged steels and powdered metal. It protects the underlying metal itself from galling and deformation.
