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.

In other words, the process entails actual chemi- cal reaction between the metal and the Bonderizing chemicals, whereby the surface is changed into a composition that is insoluble in water and hence highly resistant to the effects of moisture. With this data before us, we can more intelligently recommend the type of equipment that will best meet your needs.

OttTJ well adapted to ptoi iding i paint holding rOeiOfl resistm.

The crystalline coating produced provides the bonderising type of base for paint finishes and being integral with the metal itself, it assures greater adhesion than any other available known type of finish. While cleaning is not a part of the Spra-Bonderiz- ing Process, yet, like all other metal-finishing pro- cesses, a clean surface is necessary for satisfactory results boneerizing cleaning is included in the set-up as one of the normal operations in a completely mechanized line.

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. It seeks out prcoess creeps through microscopic openings in the finish and sets up corrosion until the whole panel is affected.

Any piece of steel will develop electro-positive and electro- One cm never all before testing just where these O-negative and electro-positive areas will occur, but we have never tailed to get a strong test for us iron at one area bonddrizing a strong test for hydroxy] ion. The ultimate result was that Clark W. The equipment is assembled in a steel housing with reservoirs below, where solutions are accumulated, ready for circulation. The Bonderizing Chemical is the result of exhaustive research in our own laboratories and practical application to actual production, and contains every element necessary to making a highly efficient rust-proofing solution.


Knowing this, manufacturers devote chapters or sections in their sales manuals to the merits of their Bonderized finish.

Bonderizing Suppliers

With this continuous barrage of in- formative advertising coming to the attention of the buying public — to en- gineers, architects, maintenance men, merchandising managers or the house- wife who buys home equipment, the manufacturer who uses the Parker Pro- cess presents this extra feature to an informed audience that knows and fully appreciates the extra rust-free service that can be expected of the Parker-protected equipment that is of- fered for consideration.

Patent 1,for an improved manganese phosphating Parkerizing technique.

Quite frequently installations are of bnoderizing s. Alternatively, the Parkerized surface may be painted over with an epoxy or molybdenum finish for added wear resistance and self- lubricating properties.

Once an auto- mobile builder recognizes the value of Bonderizing, he insists on similar protection by suppliers of acces- sories such as wheels, lamps, horns, heaters, bumper brackets and scores of smaller parts.

The Bonderite coating is an insulator and conse- quently stops the flow of small electrical currem that the alkali does not migrate to the electro positive areas, and does not become sufficient! It similarly cannot be applied to steels containing a large amount of nickelor on stainless steel.

With all the essential 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.

Definition & Meaning Bonderizing

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.


The breakdown of the test piece is usually characterized by the flaking of the finish from in- creasingly large areas as the test progresses. Bonderized piece was in good condition at hours, while finish was definitely broken on non- Bonderized piece at hours. It is especially adapted to treating forgings, cast- ings, stampings, screw machine and wire products, on which paint finishes arc not neces- sary or desirable.

It is a non-conductor of electrical currents, affording protection from electro- chemical corrosion of the metal.

Producers have found that prospective buyers are impressed with this added quality and take special pains to see that they are informed of this unseen value. The fact that enough hydroxyl ion will concentrate at an electro-positive area to neutralize so much free acid gives some idea of how important the formation of alkali is from a paint standpoint. Bonderizing provides resistance to both of these hazards through greatly improved ad- hesion of the paint and by protecting the metal from the moisture that may pene- trate the paint film.

Welcome to the most trusted and comprehensive Bonderizing directory on the Internet. These associated foreign companies are prepared chemicals for the development of the rust-proofing so the manufacturer who may not want to install equip All of them are prepared to furnish a technical ad the Parker Processes: Like all metal finishing methods, Bonderizing requires a clean surface and in both types of Bonder izing installations, the proper cleaning and rinsing equipment is usually included in the installation plans.
