Bonderizing is a chemical process to help prevent the corrosion of iron, steel, and other metals. You can also add a definition of Bonderizing yourself The process of treating a metal surface with a zinc phosphate coating in preparation for painting or. Bonderizing Process. Lubricating film for cold forging of aluminum-based metal. Our automatic processing line for aluminum-based metal has been in operation.

This department has had experience in the layout and operation of scores of rust-proofing p, antsboth large and small. After giving the product its standard finish, it is then subjected to bojderizing scientific accelerated tests, beside any other type of finish with which compari- son is to be made.

Now processing is accomplished by spraying the Bonderite solution onto the production as it passes through different chambers on a completely mechan- ized conveyor line, including cleaning, Bonderizing, rinsing and drying.

As tests ma] cover a 25 to day period, the accumulation of pieces under observation may be considerable. ISO Not Specified. The processing bath is prepared by mixing the concentrated Bonderite chemicals with water, in which the cleaned production is immersed for a suf- ficient length of time to produce the characteristic phosphate coating. There is no obliga- tion. With all the nonderizing ingredients for renewing the processing bath combined in a single, ready- mixed compound, the operator deals with only two elements, the Bonderizing Chemical and water Which reduces the DOSSibilitj of error to the absolute minimum.


A long time favorite of the rainwater goods industryzinc phosphate provides the perfect surface for field painting of bonderuzing, gutters, downspouts, and other roofing materials, as well as signs and even enamel coated interior fixtures.

Once the process is installed in the manufacturer’s production line, it becomes subject to periodical checking by expert practical operators from the Parker staff.

Colquhoun of the Parker Rust-Proof Phosphating Company of America then filed another improved phosphating patent application in Rust will not creep back under the paint film, damaging a wider area. The non-Bonder- ized piece at left indi- cated very bad blistering at the end of hours.

Cold inside and warm out- side induce condensation, unless perfect insulation can be provided, which is not always the case. For modern phosphating, see Phosphate conversion coating. The considerable list of Bonder ite users is being extended rapidly. Bonderiziny is another Parker Process that is applicable to a wide variety of articles, which still further extends the Parker service.

Panels and finishing are identical except that the test panel at the left was acid cleaned, while the panel at the right was Bonderued before finish mg. This new, more environmentally friendly coating is referred to as a vanadate conversion coating. Bonderized piece was in good condition at hours, while finish was definitely broken on non- Bonderized piece at hours. New Jersey – North.

Coatings Corrosion prevention Metalworking. Both panels were given typical refrigerator finish. Fin- ish on degreased sample be- gan to show effect of test at about 70 hours.


Patent 1, in It removes the last traces of grease or drawing com- pounds, neutralizes any residual alkali or surface rust remaining on the work, and eliminates hand marks that may have accumulated prior to pro- cessing. For more than a generation they have been educated in the extra service that may be expected of the Parker-protected product.


The conditions surrounding refrigerators are espe- cially conducive to rust.

Spra-Bonderizing supersedes and replaces the older conveyor system, bonderizlng the production was passed through a huge tank of processing solution.

The Bonderizing tank should be insulated to con- serve heat and fitted with heating units of sufficient size to maintain the solution at degrees F.

Parkerizingbonderizingphosphatingor phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating. Slight rust ap- pears where metal was exposed, but no spread- ing of corrosion or alkali to surrounding area has taken place.

This process then converts the bare galvanized surface to an inert, crystalline zinc phosphate which is subsequently rinsed and sealed with a dried-in-place chromate conversion coating. The grain size of the zinc phosphating is usually the smallest among the three processes, providing a more appealing cosmetic appearance in many applications. Bonderizing is a modern development, designed to keep step with fast moving industries.

Finishes on steel sash must successfully resist both outdoor exposure and humidity.

The Parkerizing process cannot be used on non-ferrous metals such as aluminiumbrassor copper.
