Convenient - Easy to do in house. No waiting for heatup
of blackening solution. No waiting for the unpredictable
return of parts from an outside vendor. Eliminates high
outside vendor costs. Retain control of production and
quality. Ideal for high volume or short runs. Works
especially well for blackening large volume of small
parts in a rotating barrel.
Higher Productivity - Parts can be blackened in two
minutes vs 15 to 30 minutes for hot oxide. Normally
twice the amount of parts can be blackened in the same
amount of time as with hot oxide.
Controllable - Long bath life, blackening solution
may be replenished indefinitely with periodic additions
of fresh concentrate.
So easy to install and use that you can now economically
apply a pleasing decorative, sales-appealing black corrosion-resistant
finish on parts previously left unfinished.
Versatility - Blackens cast iron, forged steels, mild
steels, hardened tool steels and powdered metal parts.
No white salt bleedout as is common with hot oxide.
Dimensional Control - No heat distortion. No smutty
rub-off as with other room-temperature blackening processes.
Energy Cost Saving - Blackening is done at room temperature
vs hot oxide blackening done at 290°F.
Safety - Blackening solution uses odorless, mild water-dilutable
chemicals that require no venting vs hot oxide. No hazardous
caustic chemicals with fumes that present health hazards
and no spattering of hot, skin-burning chemicals.
Low Maintenance - Longer Equipment Life
- No expensive pollution control equipment.
Parts Coverage - 600 to 1200 sq. ft. of
surface area blackened per gallon of concentrate.
How to achieve professional results in minutes:- Thoroughly
clean the part to be blackened by either sandblasting,
wire brushing, wire wool abrasive cleaning, or by scrubbing
in 'VIM' or 'COMET' household abrasive cleaner. Make
sure you have removed all rust, paint, oil and grease.
Immerse the part in the mixed Black Oxide Solution
and swirl around for between 30 seconds and 5 minutes.
Alternatively, the part may simply be placed in the
solution for 5 - 10 minutes. Remove the part from the
solution and rinse in fresh water.
Immediately brush on or dip into the Penetrating Sealant,
and allow to soak in the liquid for 5-10 minutes. Shake
off any excess and allow to dry thoroughly before handling.
Penetrating Sealer imparts a slightly oily feeling to the parts. If a non-oily finish is desired, do not use the Penetrating Sealer after blackening, and instead use Caswell Sealer.
Black Oxide works on steel or iron parts only and
will not blacken Stainless Steel - use Stainless Steel Blackener.
