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.

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. Bonderizint if similar recipes for stovetop kitchen Parkerizing circulate in gun publications at times, and Parkerizing kits are sold by major gun-parts distributors such as Brownells.

A II test panels arc icraicbed before heme. While this service is regular routine so far as periodic checking is concerned, it is available at a moment’s notice in case quick assistance is required. 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 and a strong test for hydroxy] ion.

Manganese phosphating, even with these process improvements, still required the use of expensive and difficult-to-obtain manganese compounds. 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. Bonderizing eliminates, so far as possible, the human element in obtaining a satisfactory surface for painting.

Next to actual service tests, outdoor bonderiznig tests are the most reliable for estimating the durability, or useful life of paint films.

The conditions surrounding refrigerators are espe- cially conducive to rust. The gasoline pump cabinet is benefitted by Bonderizing for two reasons: Bonderized piece was in good condition at hours, while finish was definitely broken on non- Bonderized piece at hours. Millions of consumers have seen Parker advertising in bonderzing Saturday Evening Post, Colliers, Time, and other na- tional magazines until Parker Pro- cesses have become synonymous with rust-proofing in the minds of buyers of automobiles, household equipment, of- fice equipment, electrical devices, and hundreds of other articles on which rust is apt to affect operating efficiency and finish appearance.

There is no obliga- tion.

Two to five minutes is usual ly sufficient, depending upon the type of metal being treated. As a result, in recent years, new, emerging technology alternatives to traditional phosphate coatings have started to see limited use, for replacing all phosphating coatings, including Parkerizing.

The difficulty of maintaining paint finishes is due to three main causes: Patent 2,just prior to the loss of easy access to manganese compounds that occurred during World War II. Finishes on steel sash must successfully resist both outdoor exposure and humidity.


Besides bonderizinh coatings, arsenate coatings may theoretically provide similar protection, at the risk of being a health hazard to humans and animals. Zinc phosphating results in a non-reflective, light- to medium-gray finish. It is also used extensively on automobiles to protect unfinished metal parts from corrosion.

Iron phosphating, zinc phosphating, manganese phosphating, powder coating, hardcoating, bright tin, nickel, zinc, sulfamate nickel, high-med-low phosphorus electroless nickel, passivate, chemfilm, phosphating rack up to 12 ft. As the work progresses on the conveyor line through the various steps of cleaning, Spra-Bonder- izing and rinsing, it proocess a series of standpipes equipped with spray nozzles through which the solution is forced against the material from every conceivable angle, flooding all areas to be treated.

With this continuous barrage of in- formative advertising coming to the attention of pprocess 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 honderizing extra rust-free service that can be expected of the Parker-protected equipment that is of- fered for consideration.

What is Bonderized Steel?

The most popular of these fluorozirconium-based conversion coatings, introduced inincorporates the transition metal vanadium. 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.

Recent wide development of zinc alloy and zinc surfaced bonderixing, to which paint, enamel or lacquer are to be ap- plied, widens prrocess scope of utility of Parker Processes and greatly extends their field of useful service.

This will enable us to give you prlcess sugges- tions, either personally or by mail, that will apply to your finishing problems. Traditional iron phosphate, zinc phosphate, and manganese phosphate chemical conversion coatings, including Parkerizing variations, have all been criticized [2] in recent years for introducing phosphates into surface water systems, encouraging the rapid growth of algae eutrophication. Once the process is installed in the manufacturer’s production line, it becomes subject pricess periodical checking by expert practical operators from the Parker staff.

Since its introduction inBonderizing has found its way into the finishing systems of hundreds of the largest manufac- turing plants in the world, where the products require the greatest measure of protection and finish beauty.

This work is handled by practical finishing experts and trained technicians. 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. The breakdown of the test piece is usually characterized by the flaking of the finish from in- creasingly large areas as the test bonderiznig. Environmental Protection Agency Recommendations. The set-up for immersion Bonderizing will ordi- narily include a heated tank for alkali cleaning, a heated tank for clear water rinse, the Bonderizing bondeizing, followed by another hot water rinse and a final hot chromic proxess rinse.


Finish is the first thing the prospective buyer sees and the way it lasts and maintains fine appearance and procesd protection is vital. These accelerated tests reveal in days what it might take years of actual weathering to find out. Important Bon- derizing applications include automobile bodies, wheels, fenders and hoods, as well as refrigerators, sterilizing and medicine cabinets and numberless other products of similar character as well as window sash and galvanized sheet steel.

Seattle, Wash Soule Steel Co. Slight rust ap- pears where metal was exposed, but no spread- ing of corrosion or alkali to surrounding area has taken place. Ve as to require engineering service, procews in locating the equipment and the development of economical time- saving methods.

Bonderizing Process

The amount of Bonderite required to vonderizing the bath back to normal chemical concentration is de- termined by a simple titration test that is easily accomplished by the operator. 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.

In addition, there are many accessory manufac- turers who adopt Bonderizing, not to meet manu- facturer’s specifications, but as a sound quality fea- ture of a well-manufactured product.

WHILE Bonderizing was originally designed to produce a rust-inhibit- ing phosphate gonderizing 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 bonserizing galvanized, galvannealed, zinc alloy and cadmium surfaces.

Go to Navigation Go to Content. The process was first used on a large scale in the manufacture of firearms for the United States military during World War II. The Stolle Corporation, W. New York – Metro. Of all the products to which Bonderizing is ap- plied, none of them demonstrate its rugged char- acter quite so forcefully as its bonderiziny on the automobile.

This entire process creates what is called a Bonderized surface. Control of the processing bath is the same as that followed in the immersion method. 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.
