Birchwood Technologies’ PRESTO BLACK BK-1 Mini system imparts finish on small part quantities

Birchwood Technologies offers the BK-1 Mini PRESTO BLACK® finishing line for protecting small quantities of iron and steel parts from corrosion.

The room-temperature blackening system for iron and steel is suitable for small production operations that require robust corrosion resistance and galling protection on critical surfaces. The 15-minute process produces a coating of less than 0.5 micron thickn that provides high corrosion resistance tested for up to 800 hours of humidity exposure when sealed with an appropriate rust preventive.
