Metal Pretreatment
Are you looking to reduce water usage, reduce chemical cost, lower energy consumption, improve salt spray results, extend bath life, or even possibly eliminate steps in your pretreatment process?
DuBois has a team of engineers, chemists, applications specialists, and field technologists waiting to help. Whether you are preparing your parts for coating by hand, or through a multimillion dollar system, we will be able to help ease your mind and take some the pressure off that comes with running any pretreatment process.
Our complete line of metal pretreatment products include:
- A wide selection of cleaners
- Iron phosphate for recirculating spray, immersion, pressure, & steam wand
- Zinc phosphate for recirculating spray and immersion
- Nonchrome final seals
- Zirconium and other phosphate-free pretreatment options
Secure iron phosphatizing products in conjunction with DuBois metal cleaners and patented final sealing rinses have been proven to provide over 1000 hours salt spray resistance with many paints and powder coatings. Additionally, DuBois has systems tailored specifically for preparing non-ferrous metals such as; aluminum, galvanized steel, galvanneal, and zinc diecast for coating(s).
DuBois LINK treatment products are widely used in the market to dramatically increase salt spray corrosion resistance and enhance coating adhesion. By LINKing the resin in the paint to the surface of the metal, we enhance the performance of your finished good. In many instances, facilities have been able to eliminate the iron phosphate step of their pretreatment process when incorporating LINK chemistry.
Perma-Gard zinc phosphating provides heavy, light, or microcrystalline zinc phosphate conversion coatings. Our highly trained and experienced team can analyze your zinc phosphatizing needs and develop a plan of action to improve and enhance your zinc conversion coating processes. System performance appraisals are available free of charge. In addition for prepaint, DuBois offers zinc phosphates for rubber to metal bonding, rust inhibition, and cold forming zinc applications.
DuraTEC 100 is a zirconium metal pretreatment replacement for iron phosphate. It is low-foaming, reduces sludge and scale, and minimizes the amount of maintenance required to operate at peak effiency. It is part of the Zirconization Process that helps protect the environment as a green alternative to phosphate. DuraTEC is now ACT test panel's standard for Zirconium.
