Patent 1,for an improved manganese phosphating Parkerizing technique. Bonderized sample showed good condition up to hours, while non-Bonder- ized sample began precipi- tous breakdown at about hours.

The Parkerizing process cannot be used on non-ferrous metals such as aluminiumbrassor copper. To offset the effects of constant weather exposure and to resist the action of the various fumes to which the finish is subjected. Due to the short processing time, equipment re- quirements are minimized, less floor space is needed, and, by recirculating the solution, it is possible to process a given amount of work with a smaller volume of working solution.

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 around the injury. 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. Ve as to require engineering service, hoth in locating the equipment and the development of economical time- saving methods.

Bonderized steel, also referred to as paint grip steel, is galvanized steel that has been put through a phosphate bath and a chromate dry. Bonderizing is a modern development, designed to keep step with fast moving industries. 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. It is especially adapted to the needs of the manufacturer whose production requirements are limited.


This process produces the dull grey color characteristic of paint grip galvanized steel which provides an excellent “primer” for painting applications. 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.

As the chemical strength of the bath is depleted, it is restored by the addition of Bonderite replenish- ing chemical. It was to overcome the first two of these difficulties of finish maintenance that Bonderizing was de- veloped. The Stolle Corporation, W. Galvanized panel identi- cal with panel at left, ex- cept that it was not Bon- derized before applying the lacquer. It is giving point and value to the manu- facturer’s statement: No matter where you are located you are only a few hours distant from adequate Parker service.

There are, of course, many detailed variations to fit them to the physical and production require- ments, but such variations are worked out in advanOl b the Parker technical staff.

Knowing this, manufacturers devote chapters or sections in their sales manuals to the merits of their Bonderized finish. New York – Metro. Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and pocess 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.

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. Parker, along with his son Wyman C. 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. Their knowledge of short-cuts and experience in meeting especially difficult or obscure finishing con- ditions is available to the user of Bonderizing.

Others make a considerable point of it in their publi- cation advertising. Parkerizing, the original Parker Process, is improved and modernized to meet today’s in- dustrial conditions.


Zinc phosphating results in a non-reflective, light- to medium-gray finish. 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.


Normally, production passes immediately from the Spra-Bonderizing section to dual rinsing, and then to final finishing. British Australian Lead Mfg. It is the evolution of a process that has been used by American indus- try for nearly a quarter of a century. With this data before us, we can more intelligently recommend the type of equipment that will best meet your needs. As these service men visit hundreds of processing installations during a year, they have accumulated a fund of metal cleaning, processing and finishing information that is invaluable to the operator whose opportunities for varied experience are bohderizing.

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. In some cases special advertising pieces are devoted entirely to the mat- ter of rust-proofing. It seeks out and creeps through microscopic openings in the finish and sets up corrosion until the whole panel is affected.

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. The breakdown of the test piece is usually characterized by the flaking of the finish from in- creasingly large areas as the test progresses. Parkerizing has a broad field, because of its simplicity, economy, adaptability and rust- proofing efficiency. This patent was issued as U.
