Birchwood Technologies’ BK-1 Mini Presto Black finishing line is designed to protect small quantities of iron and steel parts from corrosion while providing a black finish.

A low-cost alternative and/or substitute for large-scale finishing, the blackening system for iron and steel is well-suited for small production operations, the company says. It produces a virtually non-dimensional coating of less than 0.5 micron thickness, and has been tested for as many as 800 hours of humidity exposure when sealed with an appropriate rust preventive.

Unlike hazardous hot oxide methods, this process operates a room temperature. The system contains seven tanks and covers, a hot-plate (for heated cleaning), plus all the chemicals needed to operate a 5-gallon blackening line, including Presto Black MKP, Presto Black RPL and Dri-Touch Plus IRP3 water displacing sealant.
