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.

These accelerated tests reveal in days what it might take years of actual weathering to find out. Patent 2,that improved upon the zinc phosphatizing Parkerizing process further. The steaming, humid atmosphere of the kitchen or res- taurant is especially corrosive.

All units of the installation, including cleaning, processing and rinsing are usually placed in line so that one overhead track and hoist will serve for all the tanks. The considerable list of Bonder ite users is being extended rapidly. Both tested for the same length of time.

Bonderized sample showed good condition up to hours, while non-Bonder- ized sample began precipi- tous breakdown at about hours. Bonderized steel, also referred to as paint grip steel, is galvanized steel that has been put through a phosphate bath and a chromate dry. It is insur- ance to the customer that he will gel the greatest possible service from his rust-proofing investment. Finish is the first thing the prospective buyer sees and the way it lasts and maintains fine appearance and adequate protection is vital.

Many of us have seen the paint, enamel or lacquer chip and peel off our prized possessions, because the manu- facturer failed to provide a rust-pre- venting paint base- for his final finish, all of which could have been avoided had the manufacturer taken proper precautions in surface preparation he- tore the finish was applied. Spra-Bonderizing supersedes and replaces the older conveyor system, whereby the production was passed through a huge tank of processing solution.

We also offer galvannealed steelan alternative to bonderized steel, which is a prlcess steel coated with zinc on both sides by the continuous hot-dip process. The process was first used on a large scale in the manufacture of firearms for the United States military during World War II. For more than a generation they have been educated in the extra service that may be expected of the Parker-protected product.


With this knowledge of what actually takes place under the paint film when applied to steel, obviously something besides efficient cleaning and high-quality paint is necessary to fix the coating and prevent premature failure. In fact, each year sees further extensive use- of this protective process on a greater number ptocess parts as it is applied to bodies, hoods, mouldings and wheels.

Retrieved from ” https: In addition to this elaborate laboratory equipment Parker has facilities for applying all their processes under actual production conditions, as well as testing devices with which to determine the comparative rust-resistance of the coatings produced.

Colquhoun of the Parker Rust-Proof Phosphating Company of America then filed another improved phosphating patent application in Galvanized panel identi- cal with panel at left, ex- cept that it was not Bon- derized before applying the lacquer.

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

The Bonderized panel remained in good condition for nearly hours, while the finish on the non-Bonderized piece was completely destroyed in a trifle over hours. Finish quality may make or lose the sale. What is Bonderized Steel? The ultimate result was that Clark W. Call View Supplier Save Shortlist. Corrosion of the underlying metal, lack of adhesion of the paint film to the metal, bonrerizing the durability of the organic paint film itself.

No matter where you are located you are only a few hours distant from adequate Parker service. For the wine term, see Robert M.

The equipment is assembled in a steel housing with reservoirs below, where solutions are accumulated, ready for circulation. The high concentration of these chemicals per- mits packing a large amount of rust-proofing energy in a comparatively small container, thus reducing storage facilities and freight costs to a minimum.

The Soak test consists of immersing the samples in water, maintained at F. Production painting services also available.

The majority of these newer conversion coatings are fluorozirconium-based. Metallgesellschaft, Brocken- heimer Anlage Figure 2 is a Bonderized steel panel with two coats of baked enamel, pricked and subjected to hours in the salt spray. Parker service does not end with the sale of the bonderizzing and installation of equipment, but follows through as long as the manufacturer makes use of it.

Parkerizing is also a chemical conversion process, whereby the surfaces of iron or steel are changed to an insoluble phosphate coating that is highly resistant to corrosion when com- bined with stain, oil and bonderiziing finishes.


The breakdown of the test piece is usually characterized by the flaking of the finish from in- creasingly large areas as the test progresses. The terms ParkerizingParkerizeand Parkerized are all technically registered U.

Parkerizing – Wikipedia

This is a continuing free service pro- vided to assure the manufacturer the greatest possi- ble benefit from the rust-proofing operation. Parker Processes give the product a selling advantage over competing lines that are less carefully finished. Pittsburgh Electro Galvanizing Co. As for other chemical conversion coatings, the Parkerized surface must be completely covered with a light coating of oil to maximize corrosion and wear resistance, primarily through reducing wetting action and galvanic action.

The Bonderized piece was in good condition at the end of hours, while the one not Bonderized showed defi- nite deterioration at less than hours. It is especially adapted to the needs of the manufacturer whose production requirements are limited. Bonderizing, especially, is an invisi- ble quality that must be exploited to be of greatest sales and advertising value and the smart salesman can make it a distinct selling aid, if he will take pains to bring it to the prospect’s at- tention.

Parker acquired the rights to Coslett’s and Richards’ U. Views Read Bonderizig View history. Blue areas indicate dissolv- ferrous iron. Whether your customers are consum- ers or industrial users, rust-proofing and finish durability are tangible, con- structive features that indicate careful, conscientious building in all details. More than that, should the paint film be scratched or dented so that bare metal is exposed, the Bon- derite coating retards the spread of rust and the development of alkali through electro-chemical ac- tivity bondderizing the injury.

Al- most always the need for a solution of his problem is such that he is unable to await the result of tests of prospective finishes or processes under atmos- pheric conditions. It is a non-conductor bonserizing electrical currents, affording protection from electro- chemical corrosion of the metal. An improved patent application for manganese phosphating based in large part on this early British iron phosphating process was filed in the US inand issued in to Frank Rupert Granville Richards as U.
