Zirconization™ Update: Introducing DuBois Chemicals, DuraTEC 110 Nonphosphate Cleaning and Pretreatment Solutions for Ferrous and Nonferrous Parts
Nonphosphate pretreatment systems are gaining broader acceptance in the market place. Public opinion, regulatory compliance, and environmental stewardship are moving manufacturers away from phosphate-based chemistries.
Alternative Pretreatment Technologies for Steel and Aluminum Surfaces
This informative webinar program will cover current environmentally acceptable alternative pretreatment processes for steel and aluminum surfaces. It will: identify and define conversion coatings; discuss the basics of a zinc phosphate process for ferrous and aluminum surfaces; outline the advantages and disadvantages of zinc phosphate; and delve into the pros and cons of alternative technologies, such as zirconium, titanium, and silane. Ron Joseph, Organic Coatings Editor for Metal Finishing, moderates.

Lessons from the Laundry: Recovering Energy Costs with Heat Wheels
In 2008, when a barrel of oil cost $147 and a gallon of gasoline cost $4.25 (or more), many readers called or wrote to ask if there were more energy-efficient cleaning processes. They wanted an aqueous cleaning process that would operate at room temperature so that energy would not be needed to heat water, given the high, specific heat requirements in such applications.
Controlled Cleaning by Measuring Surfactant Concentration
The process reliability of pretreatment methods is the basis for high-quality products in the production of metal parts with special surface requirements. The cleaning process is the essential step between the finished shape forming and subsequent surface treatment and surface coating, respectively. Deficiently cleaned parts cause defects in the surface quality of products, leading to high costs due to consequential damages. The proper maintenance of defined concentrations of components, surfactants, and builder ensures optimal results in aqueous cleaning processes.
Troubleshooting Your Ultrasonic Cleaning Process
Ultrasonic cleaning—that is, cleaning with high-frequency sound waves—is not a miracle cure; it just seems like one. When properly used, adding ultrasonics to the cleaning process enhances the efficiency of surface preparation processes, provides superior soil removal, lowers the rework rate, and increases profits.
