Being in many cases continually exposed to the weather and under the necessity of presenting a fine finish appearance for a number of years, Bonderizing provides better finish protection than can be secured in any other way. Patentbonderizingg New York – Metro. 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 tank, followed by another hot water rinse and a final hot chromic acid rinse.
Immediately upon receipt of these samples a competent engineer will give jour prob- lem careful study. Go to Navigation Peocess to Content. It is bonderiizng adapted to the needs of the manufacturer whose production requirements are limited.
Alternatively, the Parkerized surface may be painted over with an epoxy or molybdenum finish for added wear resistance and self- lubricating properties. Each installa- tion is engineered to fit the special production requirements of the user. Corrosion of the underlying metal, lack of adhesion of the paint film to the metal, and the durability of the organic paint film itself.
This is a part Of our sales service Your finishing executives are invited to be present When vour samples lrocess processed, to observe how these, as well as other products, are treated W e will arrange comparative durability tests in our labor.
The earliest work on phosphating processes was developed by British inventors William Procees Ross, British patentinand by Thomas Watts Coslett, British patentin This laboratory’ bohderizing also fitted with a paint sprav booth, as well as an electricalK heated, thermostaticall con- trolled, high temperature baking oxen tor drying paini finishes over Parker COatingS, preparat.
It not only provides for better ad- hesion and durability of finishes applied over it, but provides a check on cleaning operations as well. Our materials are supplied at prices and on terms established by us h prices and terms are uniform and without discrimination among all users.

Parkerizing, the original Parker Process, is improved and modernized to meet today’s in- dustrial conditions.
Quality Certifications ISO So important is this regarded by many manufacturers procrss they devote space in their catalogs, booklets and folders to the item of rust-proof fin- ishes. The Bonderizing Process is not only used more extensively on sheet metal units requiring a type of finish that will provide a high processs of rust resistance and maintain fine appearance over a period of years, but is now so improved as to widen its scope of effectiveness to include hot rolled steel, zinc coated surfaces, and zinc base die castings.
The differ onl in the type I Qdamentally, and for all tical purposes the chemical reaction, eating produced and rust-proofing results are the same.
