This is Activator Type I formulated specifically for use with the “Dow 7”
conversion coating process for magnesium alloys. Type I is chosen for
most wrought alloys, hog-outs, and weldments. Being less aggressive
than Type II, it is formulated as the safer and easier-to-use activator option
when the aggressiveness of the Type II activator to overcome die casting skin
is not required.
Specification & Certifications:
The coating produced by proper application of this solution along with the
Dichromate solution, conforms to SAE AMS-M-3171, Type III (formerly
MIL-M-3171, Type III), sometimes referred to as “Dow 7”.
Parts containing bearings, studs, and inserts of brass, bronze, steel, cadmium-
plated steel and aluminum may be treated using this activator.
This formulation contains fluorides that are highly corrosive to skin
and bones. Use only with appropriate personal protective equipment (PPE)
which includes neoprene waders, a chemical apron, neoprene gloves,
face shield, and either a fume hood or other suitable ventilation.

This Type I activator kit includes a 1-Gallon jug of Type I concentrate packed
in a 5-gallon screw top pail. At time of use, 3 gallons of water are added to
the pail to which the 1-gallon jug of Type I activator is added. This will make
a 4-gallon immersion bath which is generally large enough to handle most small
parts. Immersion time is generally about 5 minutes in duration. When the process
is complete, simply screw the lid on the pail and store for future use.
