Mini blackening system suitable for coating small quantities of metal parts

Birchwood Technologies offers the PRESTO BLACK® BK-1 mini room-temperature blackening system. It imparts corrosion and galling protection on small quantities of iron and steel parts.

The 15-min. process produces a nearly nondimensional coating of less than 0.5 micron thickness. It is suitable for components that require a black finish for visual appeal and rust protection.

The system comprises seven tanks and covers, a hot plate (for heated cleaner), and the chemicals required to operate a 5-gal. blackening line, including 1 gal. of MKP, 1 gal. of RPL, and 5 gal. of Dri-Touch Plus IRP3 water-displacing sealant.
