The Black Oxide process by KOOL-BLAK 225 delivers a Deep, Rich, Black Oxide finish. Completely Smut Free! No Boiling Caustic Fumes! Black Oxide and Its unique rectifier eliminates the problem of colloidal red iron in the solution by flushing it to the surface where it is removed by being carried out on the work and then washed off in the rinse water. The rectified red iron may also be periodically removed from the solution by skimming. This eliminates the increased energy consumption and frequent tank clean-out which results from the iron settling to the bottom of the tank. In addition, the rectifier eliminates contamination of the solution with zinc, copper and lead by combining with these metals so they are removed on a continuous basis. Some of the benefits of using Kool Blak 225 are: 30-45 minute blackening time, Abrasion resistant: no chipping, peeling, or rub off, Beautiful, glossy blue/black color, No Boiling- safer process for machine operator, Considerable energy cost savings.
