Phosphatizer Spray is a liquid concentrate designed to produce an iron
phosphate conversion coating on bare metals. This conversion
coating provides a much better base to promote paint adhesion and yields
a coating that retards rusting. Properly cleaned and treated
ferrous parts will emerge with a metallic blue/grey coating of iron
phosphate weighing 25-40 mg/sq. ft.
Physical State - Liquid
Color - Straw to amber
Density - 9.59 lbs/gal
pH - 3.5
Although Iron Phosphatizer Spray has
deterging agents incorporated into it, parts that are heavily soiled or
contain mill scale should be cleaned and rinsed prior to phosphatizing.
Prepare a solution of 2-4 oz. of Iron
Phosphatizer Spray to 1 gallon of water. Spray it over the parts to be coated for 1/2
to 3 minutes at 90-160*F. Allow to air dry. A sealer may be
used prior to painting to further enhance the phosphate coating.
CONTROL OF BATH
Iron phosphatizing progresses best at a
pH range of 4 to 6. Initial preparation of the bath will be at the
lower end of this pH range or even slightly below. As
phosphatizing proceeds, the pH will rise finally approaching the upper
end of this range. At this time, more Iron Phosphatizer Spray
should be added. This sequence should be followed perhaps a dozen
times or until the bath becomes hopelessly fouled. The bath should
then be dumped, the tank rinsed, and a fresh solution should be prepared
at that time.
Iron Phosphatizer Spray is a concentrated
acidic solution. Do note take internally. Avoid skin and
particularly eye contact. Should contact occur, flush area with
large amounts of water. If any discomfort persists, seek medical
attention. Read relevant Material Safety Data Sheet before
handling this product.
Iron Phosphatizer Spray is packaged in 55,
30, 15, and 5 gal. non-returnable containers.
