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.

A heavy oil coating is unnecessary and undesirable for achieving a positive grip on Parkerized metal parts. Locations Served California – South.
Definition & Meaning Bonderizing
Through this national advertising, the buying public is being made “rust- conscious” and is developing a greater apprec iation of the quality appeal.
Parkerizing has a broad procezs, because of its simplicity, economy, adaptability and rust- proofing efficiency. It essentially provided an iron phosphating process, using phosphoric acid. Detroit Steel Products Co. Two to five minutes is usual ly sufficient, depending upon the type of metal being treated.
Parkerizingbonderizingphosphatingor phosphatizing is a method of protecting a ptocess surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating.
The process was bonderizibg used on a large scale in the manufacture of firearms for the United States military during World War II. 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. Parkerizing, the original Parker Process, is improved and modernized to meet today’s in- dustrial conditions.
A stream of small bubbles is emitted from the metal part as the process takes place; when the bubbling stops, the process is complete. WHILE Proces was originally designed to produce a rust-inhibit- ing phosphate coating on iron and steel only, as an integral paint base, it has been perfected to such an extent that the same corrosion resisting and paint holding qualities can be extended to galvanized, galvannealed, zinc alloy and cadmium surfaces.
This was caused by contaminants in the acid solution and not cosmoline as is commonly believed. 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.
The steaming, humid atmosphere of the bondedizing or res- taurant is especially corrosive. The considerable list of Bonder ite users is being extended rapidly.
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: The Stolle Corporation, W. From Wikipedia, the free encyclopedia. Production painting services also available.
The ultimate result was that Clark W.
Parkerizing – Wikipedia
The grain size of the zinc phosphating is usually the smallest among the three processes, providing a more appealing cosmetic appearance in many applications. Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and not to be an improved iron phosphating process, although some use the term parkerizing as a generic term for applying phosphating or phosphatizing coatings that does include the iron phosphating process.
To make sure that all moisture is eliminated from seams, cracks and crevices, a dry-off oven is included at the end of the line. The terms ParkerizingParkerizeand Parkerized are all technically registered U. To meet this condition, various accelerated labora- tory tests have been devised to create in a matter of days the effects that might require years of weather- ing to produce. Of the several accelerated tests used in checking finishes on metal, the salt spray takes a prominent part and large capacity is prov ided for this purpose.
With these process improvements, the end result was that a low-temperature energy-efficient zinc phosphating Parkerizing process, using strategic materials to which the United States bonderizint ready access, became the most common phosphating bonferizing used during World War II to protect American war materials such as firearms and planes from rust and corrosion.
Bonderized Steel Process In a continuous, controlled process, coils of galvanized steel are first thoroughly cleaned and rinsed. It is especially adapted to the needs of the manufacturer whose production requirements are limited. Bonderized steel, also referred to as paint grip steel, is galvanized steel that has been put through a phosphate bath and a chromate dry. Colquhoun of the Parker Rust-Proof Phosphating Company of America then filed another improved phosphating patent application in 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.
While the complete process is standardized procesz far as procedure is concerned, there is no “standard” style, size or shape of tank equipment. Specializing in black oxide finishing. ISO Not Specified. Give us a call at or contact us online and get a quote today! While there are many different tests for checking the comparative resistance of various coatings, the salt spray obnderizing humidity tests have been widely adopted by industry in checking enamels and lacquers.
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.
A broad range of Bonderizing resources are compiled in this industrial portal which provides information on manufacturers, distributors and service companies in the Bonderizing industry. Ohio I tetroic, Mich. Thus it becomes possible in all Bonder- izing installations to treat entirely fer- rous metal production, entirely zinc, galvanized, galvannealed or cadmium sur- faced production, or any percentage mix- ture of these metals.
